Description



[0001] The present invention relates to the field of vaccination, in particular to cancer vaccines.

[0002] The immune system can recognize and to some extent eliminate tumor cells, however, this anti-tumor response is often of low amplitude and inefficient. Boosting this weak anti-tumor response with therapeutic vaccination has been a long sought goal for cancer therapy. Modulating the immune system to enhance immune responses has thus become a promising therapeutic approach in oncology as it can be combined with standard of care treatments.

[0003] Promising preclinical data and advances in clinical trials, including the recent FDA approval of the Sipuleucel-T vaccine and of the anti-CTLA-4 antibody, show that active immunization is a safe and feasible treatment modality for certain cancer types. Induction of tumor-specific cytotoxic T lymphocytes (CTLs) mediated immune responses has been reported using different approaches including modified tumor cell vaccines, peptide vaccines, recombinant viral vectors, DNA, protein, or dendritic cell vaccines. However, the anti-tumoral immunity mediated by CTLs only occasionally correlates with tumor regression and only a few projects have reached the phase III clinical stage.

[0004] Overall, cancer vaccines showed very limited clinical efficacy so far. Indeed, at the end of 2011, amongst the 300 hundred ongoing cancer vaccine clinical trials, only 19 phase III trials were reported (globaldata, 2014. Amongst them, there are NeuVax, a peptide vaccine for breast cancer, Stimuvax, a liposome based vaccine for Non-Small Cell Lung Carcinoma (NSCLC) and breast cancer, TG4010, a vaccinia-based vaccine for NSCLC and GSK1572932A, an adjuvanted liposome for NSCLC. These four cancer vaccines are based on different technologies and have in common that they are targeting one single antigen.

[0005] Therapeutic cancer vaccines can be divided into two principal categories: personalized (autologous) and standardized vaccines, and further classified depending on the technology platform. Current personalized vaccines include tumor lysate vaccines as well as dendritic cells based vaccine (hereinafter cell based). For the latter, antigen loading can occur either with a pulse using tumor lysates, or transfection with RNA extracted from the tumors. In this case, the antigens are tumor specific or associated, but are not clearly defined. Dendritic cells can also be loaded with defined antigens either with peptide pulse or using a protein such as the Prostatic Acid Phosphatase (PAP) used to engineer the Provenge.RTM. vaccine. However, the manufacturing process of these cell-based therapies is time-consuming and labor-intensive while quality standards are difficult to reach and maintain. Immunomonitoring creates further complications. Moreover, the majority of the autologous cancer vaccines do not allow the identities or quantities of antigens used to be controlled, unlike defined and standardized vaccines.

[0006] In contrast to cell-based therapy (APCs, T cells, CARs, lysates), subunits vaccines (protein or peptides) allow the development of a standardized vaccine with an easier production and significantly better batch to batch reproducibility that can be administrated to a broad range of patients. Furthermore, the antigens are fully defined allowing for better immune-monitoring and reducing the risk of unwanted effects of vaccine component.

[0007] The different approaches which were evaluated in pre-clinical and clinical development include short peptide vaccines (Slingluff C L, Jr. The present and future of peptide vaccines for cancer: single or multiple, long or short, alone or in combination? Cancer journal 2011; 17(5):343-50), long-peptide vaccines (Melief C J, van der Burg S H. Immunotherapy of established (pre)malignant disease by synthetic long peptide vaccines. Nature reviews Cancer 2008; 8(5):351-60) and proteins. In contrast to long peptide and protein vaccines, short peptide vaccines have a very short half-life and can have negative consequences on the immune response.

[0008] For the protein-based vaccines, the results of targeting MAGE-A3 with a recombinant fusion protein-based vaccine have been enthusiastically awaited after promising phase II data in metastatic melanoma (Kruit W H, Suciu S, Dreno B, Mortier L, Robert C, Chiarion-Sileni V, et al. Selection of immunostimulant AS15 for active immunization with MAGE-A3 protein: results of a randomized phase II study of the European Organisation for Research and Treatment of Cancer Melanoma Group in Metastatic Melanoma. Journal of clinical oncology: official journal of the American Society of Clinical Oncology 2013; 31(19):2413-20) and non-small cell lung cancer (NSLC) (Vansteenkiste J, Zielinski M, Linder A, Dahabreh J, Gonzalez E E, Malinowski W, et al. Adjuvant MAGE-A3 immunotherapy in resected non-small-cell lung cancer: phase II randomized study results. Journal of clinical oncology: official journal of the American Society of Clinical Oncology 2013; 31(19):2396-403). However, in 2013 the phase III DERMA trial in melanoma (NCT00796445) did not meet its first co-primary endpoint, followed in 2014 with a stop of the phase III MAGRIT study in NSCL (NCT00480025). Despite these very disappointing clinical results, protein based vaccines undeniably present many advantages.

[0009] A therapeutic cancer vaccine is administrated to cancer patients to strengthen the capability of their immune system to recognize and kill the tumor cells. The main goal of a therapeutic cancer vaccine is to generate killer T cells (also called cytotoxic T lymphocytes) specific for the tumor cells. To this end and to achieve a potent immune response, the vaccine must contain molecules called antigens that are also present in the tumor and that need to be delivered to Antigen Presenting Cells (APCs), especially dendritic cells (DCs), to allow cancer immunity to be initiated. The DCs process these tumor antigens into small peptides that are presented on cell surface expressed MHC class I or MHC class II molecules to T cells. Peptides that are then recognized by T cells and thereby induce their stimulation are called epitopes. Presentation by MHC class I and MHC class II molecules allows activation of two classes of T cells, CD8.sup.+ cytotoxic T lymphocytes (CTLs) and CD4.sup.+ helper T (T.sub.h) cells, respectively. In addition, to become fully activated, beside antigen recognition T cells require a second signal, the co-stimulatory signal, which is antigen non-specific and is provided by the interaction between co-stimulatory molecules expressed on the surface of APCs and the T cell. Therefore two major requirements for an efficient therapeutic cancer vaccine are the specificity of the tumor antigens and the ability to deliver them efficiently to DCs.

[0010] Taken together, induction of a tumor specific immune response thus requires three main steps: (i) an antigen must be delivered to dendritic cells, which will process it into epitopes, (ii) dendritic cells should receive a suitable activation signal, and (iii) activated tumor antigen-loaded dendritic cells must generate T-cell mediated immune responses in the lymphoid organs.

[0011] Since tumor cells can escape the immune system by down-regulating expression of individual antigens (passive immune escape), multi-epitopic antigen delivery provides an advantage. Indeed, protein based vaccines allow multi-epitopic antigen delivery to antigen presenting cells (APCs) such as dendritic cells (DCs) without the limitation of restriction to a single MHC allele. Another strength is long-lasting epitope presentation recently described in dendritic cells loaded with proteins (van Montfoort N, Camps M G, Khan S, Filippov D V, Weterings J J, Griffith J M, et al. Antigen storage compartments in mature dendritic cells facilitate prolonged cytotoxic T lymphocyte cross-priming capacity. Proceedings of the National Academy of Sciences of the United States of America 2009; 106(16):6730-5). Furthermore, proteins require uptake and processing by DCs to achieve MHC restricted presentation of their constituent epitopes. This reduces the risk of inducing peripheral tolerance as has been shown after vaccination with short peptides that do not have such stringent processing requirements (Toes R E, Offringa R, Blom R J, Melief C J, Kast W M. Peptide vaccination can lead to enhanced tumor growth through specific T-cell tolerance induction. Proceedings of the National Academy of Sciences of the United States of America 1996; 93(15):7855-60).

[0012] However, most soluble proteins are generally degraded in endolysosomes and are poorly cross-presented on MHC class I molecules and are therefore poorly immunogenic for CD8.sup.+ T cell responses (Rosalia R A, Quakkelaar E D, Redeker A, Khan S, Camps M, Drijfhout J W, et al. Dendritic cells process synthetic long peptides better than whole protein, improving antigen presentation and T-cell activation. European journal of immunology 2013; 43(10):2554-65). Moreover, although mature DCs are more potent than immature DCs in priming and eliciting T-cell responses (Apetoh L, Locher C, Ghiringhelli F, Kroemer G, Zitvogel L. Harnessing dendritic cells in cancer. Semin Immunol. 2011; 23:42-49), they lose the ability to efficiently take up exogenous antigens, particularly for MHC class II restricted antigens (Banchereau J, Steinman R M. Dendritic cells and the control of immunity. Nature. 1998; 392:245-252). As a result, peptide-pulsed DCs as vaccines have several limitations. For example, peptide degradation, rapid MHC class I turnover, and the disassociation of peptide from MHC class I molecules during the preparation and injection of DC/peptides may result in short half-lives of MHC class I/peptide complexes on the DC surface, leading to weak T-cell responses.

[0013] To improve the efficacy of protein-based vaccine delivery, the use of cell penetrating peptides for intracellular delivery of cancer peptides into DCs has been proposed (Wang R F, Wang H Y. Enhancement of antitumor immunity by prolonging antigen presentation on dendritic cells. Nat Biotechnol. 2002; 20:149-156). Cell penetrating peptides (CPPs) are peptides of 8 to 40 residues that have the ability to cross the cell membrane and enter into most cell types (Copolovici D M, Langel K, Eriste E, Langel U. Cell-penetrating peptides: design, synthesis, and applications. ACS nano 2014; 8(3):1972-94, Milletti F. Cell-penetrating peptides: classes, origin, and current landscape. Drug Discov Today 2012). Alternatively, they are also called protein transduction domain (PTDs) reflecting their origin as occurring in natural proteins. Several potent CPPs have been identified from proteins, including the Tat protein of human immunodeficiency virus, the VP22 protein of herpes simplex virus, and fibroblast growth factor (Berry C C. Intracellular delivery of nanoparticles via the HIV-1 tat peptide. Nanomedicine. 2008; 3:357-365; Deshayes S, Morris M C, Divita G, Heitz F. Cell-penetrating peptides: Tools for intracellular delivery of therapeutics. Cell Mol Life Sci. 2005; 62:1839-1849; Edenhofer F. Protein transduction revisited: Novel insights into the mechanism underlying intracellular delivery of proteins. Curr Pharm Des. 2008; 14:3628-3636; Gupta B, Levchenko T S, Torchilin V P. Intracellular delivery of large molecules and small particles by cell-penetrating proteins and peptides. Adv Drug Deliv Rev. 2005; 57:637-651; Torchilin V P. Recent approaches to intracellular delivery of drugs and DNA and organelle targeting. Annu Rev Biomed Eng. 2006; 8:343-375). It was found that T-cell activity elicited by DC/TAT-TRP2 was 3- to 10-fold higher than that induced by DC/TRP2 (Wang H Y, Fu T, Wang G, Gang Z, Donna M P L, Yang J C, Restifo N P, Hwu P, Wang R F. Induction of CD4+ T cell-dependent antitumor immunity by TAT-mediated tumor antigen delivery into dendritic cells. J Clin Invest. 2002a; 109:1463-1470).

[0014] Moreover, subunits vaccines (peptides or proteins) are poorly immunogenic. Therefore in the context of therapeutic cancer vaccine, a potent adjuvant is mandatory to be added to the vaccine in order to increase the level of co-stimulatory molecules on DCs and therefore augment the immune system's response to the target antigens. Adjuvants accomplish this task by mimicking conserved microbial components that are naturally recognized by the immune system. They include, lipopolysaccharide (LPS), components of bacterial cell walls, and nucleic acids such as double-stranded RNA (dsRNA), single-stranded DNA (ssDNA), and unmethylated CpG dinucleotide-containing DNA. Their presence together with the vaccine can greatly increase the innate immune response to the antigen. Furthermore, this adjuvant should promote an adaptive immune response with CTLs and type polarized Th1 rather than a humoral immune response resulting in antibody production. Different adjuvants have been evaluated, with a limited number having gained regulatory approval for human use. These include Alum, MPL (monophosphoryl lipid A) and ASO.sub.4 (Alum and MPL) in the US, and MF59 (oil-in-water emulsion), ASO.sub.4, liposomes in Europe (Lim, Y. T., Vaccine adjuvant materials for cancer immunotherapy and control of infectious disease. Clin Exp Vaccine Res, 2015. 4(1): p. 54-8).

[0015] Recently, Toll Like Receptor (TLR) ligands are emerging as promising class of adjuvants (Baxevanis, C. N., I. F. Voutsas, and O. E. Tsitsilonis, Toll-like receptor agonists: current status and future perspective on their utility as adjuvants in improving anticancer vaccination strategies. Immunotherapy, 2013. 5(5): p. 497-511). A significant development of cancer vaccine studies was thus to include various TLR agonists to vaccine formulations, including TLR-3 (poly I:C), TLR-4 (monophosphoryl lipid A; MPL), TLR-5 (flagellin), TLR-7 (imiquimod), and TLR-9 (CpG) (Duthie M S, Windish H P, Fox C B, Reed S G. Use of defined TLR ligands as adjuvants within human vaccines. Immunol Rev. 2011; 239:178-196). The types of signaling and cytokines produced by immune cells after TLR stimulation control CD4+ T-cell differentiation into Th1, Th2, Th17, and Treg cells. Stimulation of immune cells such as DCs and T cells by most TLR-based adjuvants produces proinflammatory cytokines and promotes Th1 and CD8+ T responses (Manicassamy S, Pulendran B. Modulation of adaptive immunity with Toll-like receptors. Semin Immunol. 2009; 21:185-193).

[0016] Conjugating the vaccine to a TLR ligand is an attractive approach that offers several advantages over non-conjugated vaccines including (i) preferential uptake by the immune cells expressing the TLR, (ii) higher immune response and (iii) reduced risk of inducing peripheral tolerance. Indeed, all the antigen presenting cells loaded with the antigen will be simultaneously activated. Different groups explored this approach with various TLR ligands being mainly linked chemically to the peptide or protein vaccine (Zom G G, Khan S, Filippov D V, Ossendorp F. TLR ligand-peptide conjugate vaccines: toward clinical application. Adv Immunol. 2012; 114:177-201). As the chemical linkage to peptide is easily performed, the most highly investigated TLR ligands for conjugate vaccine are the TLR2 agonist Pam2Cys and Pam3Cys (Fujita, Y. and H. Taguchi, Overview and outlook of Toll-like receptor ligand-antigen conjugate vaccines. Ther Deliv, 2012. 3(6): p. 749-60).

[0017] However, to date the majority of cancer vaccines trials have shown limited efficacy. One explanation is the lack of a therapy that can simultaneously (i) stimulate multi-epitopic cytotoxic T cell-mediated immunity, (ii) induce T.sub.h cells and (iii) promote immunological memory. These three parameters are essential to generate potent, long lasting anti-tumor immunity. Indeed, CTLs specific for different epitopes will allow destruction of more cancer cells within a heterogeneous tumor mass and avoid the outgrowth of antigen-loss variants (tumor immune escape). T.sub.h cells are involved in the maintenance of long-lasting cellular immunity and tumor infiltration by T.sub.h cells is also an essential step for the recruitment and function of CD8.sup.+ CTLs. Immunological memory is essential to protect against tumor relapse.

[0018] In view of the above, it is the object of the present invention to overcome the drawbacks of current cancer vaccines outlined above and to provide a novel complex for cancer immunotherapy applications representing a more potent vaccine, in particular cancer vaccine, having improved anti-tumor activity.

[0019] This object is achieved by means of the subject-matter set out below and in the appended claims.

[0026] Complexes according to the Present Invention

[0027] In a first aspect the present invention provides a complex comprising: [0028] a) a cell penetrating peptide; [0029] b) at least one antigen or antigenic epitope; and [0030] c) at least one TLR peptide agonist,

[0031] wherein the components a)-c), i.e. the cell penetrating peptide, the at least one antigen or antigenic epitope and the at least one TLR peptide agonist, are covalently linked.

[0032] Such a complex according to the present invention provides simultaneous (i) stimulation of multi-epitopic cytotoxic T cell-mediated immunity, (ii) induction of T.sub.h cells and (iii) promotion of immunological memory. Thereby, a complex according to the present invention provides a potent vaccine, in particular having improved anti-tumor activity.

[0033] Preferably, the complex according to the present invention is a polypeptide or a protein, in particular a recombinant polypeptide or a recombinant protein, preferably a recombinant fusion protein or a recombinant fusion polypeptide. The term "recombinant" as used herein means that it (here: the polypeptide or the protein) does not occur naturally. Accordingly, the complex according to the present invention, which is a recombinant polypeptide or a recombinant protein, typically comprises components a) to c), wherein components a) to c) are of different origins, i.e. do not naturally occur in this combination.

[0034] In the context of the present invention, i.e. throughout the present application, the terms "peptide", "polypeptide", "protein" and variations of these terms refer to peptide, oligopeptide, oligomer or protein including fusion protein, respectively, comprising at least two amino acids joined to each other preferably by a normal peptide bond, or, alternatively, by a modified peptide bond, such as for example in the cases of isosteric peptides. A peptide, polypeptide or protein can be composed of L-amino acids and/or D-amino acids. Preferably, a peptide, polypeptide or protein is either (entirely) composed of L-amino acids or (entirely) of D-amino acids, thereby forming "retro-inverso peptide sequences". The term "retro-inverso (peptide) sequences" refers to an isomer of a linear peptide sequence in which the direction of the sequence is reversed and the chirality of each amino acid residue is inverted (see e.g. Jameson et al, Nature, 368,744-746 (1994); Brady et al, Nature, 368,692-693 (1994)). In particular, the terms "peptide", "polypeptide", "protein also include "peptidomimetics" which are defined as peptide analogs containing non-peptidic structural elements, which peptides are capable of mimicking or antagonizing the biological action(s) of a natural parent peptide. A peptidomimetic lacks classical peptide characteristics such as enzymatically scissile peptide bonds. In particular, a peptide, polypeptide or protein can comprise amino acids other than the 20 amino acids defined by the genetic code in addition to these amino acids, or it can be composed of amino acids other than the 20 amino acids defined by the genetic code. In particular, a peptide, polypeptide or protein in the context of the present invention can equally be composed of amino acids modified by natural processes, such as post-translational maturation processes or by chemical processes, which are well known to a person skilled in the art. Such modifications are fully detailed in the literature. These modifications can appear anywhere in the polypeptide: in the peptide skeleton, in the amino acid chain or even at the carboxy- or amino-terminal ends. In particular, a peptide or polypeptide can be branched following an ubiquitination or be cyclic with or without branching. This type of modification can be the result of natural or synthetic post-translational processes that are well known to a person skilled in the art. The terms "peptide", "polypeptide", "protein" in the context of the present invention in particular also include modified peptides, polypeptides and proteins. For example, peptide, polypeptide or protein modifications can include acetylation, acylation, ADP-ribosylation, amidation, covalent fixation of a nucleotide or of a nucleotide derivative, covalent fixation of a lipid or of a lipidic derivative, the covalent fixation of a phosphatidylinositol, covalent or non-covalent cross-linking, cyclization, disulfide bond formation, demethylation, glycosylation including pegylation, hydroxylation, iodization, methylation, myristoylation, oxidation, proteolytic processes, phosphorylation, prenylation, racemization, seneloylation, sulfatation, amino acid addition such as arginylation or ubiquitination. Such modifications are fully detailed in the literature (Proteins Structure and Molecular Properties (1993) 2nd Ed., T. E. Creighton, New York; Post-translational Covalent Modifications of Proteins (1983) B. C. Johnson, Ed., Academic Press, New York; Seifter et al. (1990) Analysis for protein modifications and nonprotein cofactors, Meth. Enzymol. 182: 626-646 and Rattan et al., (1992) Protein Synthesis: Post-translational Modifications and Aging, Ann NY Acad Sci, 663: 48-62). Accordingly, the terms "peptide", "polypeptide", "protein" preferably include for example lipopeptides, lipoproteins, glycopeptides, glycoproteins and the like.

[0035] However, in a particularly preferred embodiment, the complex according to the present invention is a "classical" peptide, polypeptide or protein, whereby a "classical" peptide, polypeptide or protein is typically composed of amino acids selected from the 20 amino acids defined by the genetic code, linked to each other by a normal peptide bond.

[0036] If the complex according to the present invention is a polypeptide or a protein, it is preferred that it comprises at least 50, at least 60, at least 70, preferably at least 80, at least 90, more preferably at least 100, at least 110, even more preferably at least 120, at least 130, particularly preferably at least 140, or most preferably at least 150 amino acid residues.

[0037] Component a)--Cell Penetrating Peptide

[0038] The CPP allows for efficient delivery, i.e. transport and loading, in particular of at least one antigen or antigenic epitope, into the antigen presenting cells (APCs), in particular into the dendritic cells (DCs) and thus to the dendritic cells' antigen processing machinery.

[0039] The term "cell penetrating peptides" ("CPPs") is generally used to designate short peptides that are able to transport different types of cargo molecules across plasma membrane, and, thus, facilitate cellular uptake of various molecular cargoes (from nanosize particles to small chemical molecules and large fragments of DNA). "Cellular internalization" of the cargo molecule linked to the cell penetrating peptide generally means transport of the cargo molecule across the plasma membrane and thus entry of the cargo molecule into the cell. Depending on the particular case, the cargo molecule can, then, be released in the cytoplasm, directed to an intracellular organelle, or further presented at the cell surface. Cell penetrating ability, or internalization, of the cell penetrating peptide or complex comprising said cell penetrating peptide, according to the invention can be checked by standard methods known to one skilled in the art, including flow cytometry or fluorescence microscopy of live and fixed cells, immunocytochemistry of cells transduced with said peptide or complex, and Western blot.

[0040] Cell penetrating peptides typically have an amino acid composition that either contains a high relative abundance of positively charged amino acids such as lysine or arginine or have a sequence that contains an alternating pattern of polar/charged amino acids and non-polar, hydrophobic amino acids. These two types of structures are referred to as polycationic or amphipathic, respectively. Cell-Penetrating peptides are of different sizes, amino acid sequences, and charges but all CPPs have a common characteristic that is the ability to translocate the plasma membrane and facilitate the delivery of various molecular cargoes to the cytoplasm or to an organelle of a cell. At present, the theories of CPP translocation distinguish three main entry mechanisms: direct penetration in the membrane, endocytosis-mediated entry, and translocation through the formation of a transitory structure. CPP transduction is an area of ongoing research. Cell-penetrating peptides have found numerous applications in medicine as drug delivery agents in the treatment of different diseases including cancer and virus inhibitors, as well as contrast agents for cell labeling and imaging.

[0041] Typically, cell penetrating peptides (CPPs) are peptides of 8 to 50 residues that have the ability to cross the cell membrane and enter into most cell types. Alternatively, they are also called protein transduction domain (PTDs) reflecting their origin as occurring in natural proteins. Frankel and Pabo simultaneously to Green and Lowenstein described the ability of the trans-activating transcriptional activator from the human immunodeficiency virus 1 (HIV-TAT) to penetrate into cells (Frankel, A. D. and C. O. Pabo, Cellular uptake of the tat protein from human immunodeficiency virus. Cell, 1988. 55(6): p. 1189-93). In 1991, transduction into neural cells of the Antennapedia homeodomain (DNA-binding domain) from Drosophila melanogaster was described (Joliot, A., et al., Antennapedia homeobox peptide regulates neural morphogenesis. Proc Natl Acad Sci USA, 1991. 88(5): p. 1864-8). In 1994, the first 16-mer peptide CPP called Penetratin, having the amino acid sequence RQIKIYFQNRRMKWKK (SEQ ID NO: 1) was characterized from the third helix of the homeodomain of Antennapedia (Derossi, D., et al., The third helix of the Antennapedia homeodomain translocates through biological membranes. J Biol Chem, 1994. 269(14): p. 10444-50), followed in.1998 by the identification of the minimal domain of TAT, having the amino acid sequence YGRKKRRQRRR (SEQ ID NO: 2) required for protein transduction (Vives, E., P. Brodin, and B. Lebleu, A truncated HIV-1 Tat protein basic domain rapidly translocates through the plasma membrane and accumulates in the cell nucleus. J Biol Chem, 1997. 272(25): p. 16010-7). Over the past two decades, dozens of peptides were described from different origins including viral proteins, e.g. VP22 (Elliott, G. and P. O'Hare, Intercellular trafficking and protein delivery by a herpesvirus structural protein. Cell, 1997. 88(2): p. 223-33) and ZEBRA (Rothe, R., et al., Characterization of the cell-penetrating properties of the Epstein-Barr virus ZEBRA trans-activator. J Biol Chem, 2010. 285(26): p. 20224-33), or from venoms, e.g. melittin (Dempsey, C. E., The actions of melittin on membranes. Biochim Biophys Acta, 1990. 1031(2): p. 143-61), mastoporan (Konno, K., et al., Structure and biological activities of eumenine mastoparan-AF (EMP-AF), a new mast cell degranulating peptide in the venom of the solitary wasp (Anterhynchium flavomarginatum micado). Toxicon, 2000. 38(11): p. 1505-15), maurocalcin (Esteve, E., et al., Transduction of the scorpion toxin maurocalcine into cells. Evidence that the toxin crosses the plasma membrane. J Biol Chem, 2005. 280(13): p. 12833-9), crotamine (Nascimento, F. D., et al., Crotamine mediates gene delivery into cells through the binding to heparan sulfate proteoglycans. J Biol Chem, 2007. 282(29): p. 21349-60) or buforin (Kobayashi, S., et al., Membrane translocation mechanism of the antimicrobial peptide buforin 2. Biochemistry, 2004. 43(49): p. 15610-6). Synthetic CPPs were also designed including the poly-arginine (R8, R9, R10 and R12) (Futaki, S., et al., Arginine-rich peptides. An abundant source of membrane-permeable peptides having potential as carriers for intracellular protein delivery. J Biol Chem, 2001. 276(8): p. 5836-40) or transportan (Pooga, M., et al., Cell penetration by transportan. FASEB J, 1998. 12(1): p. 67-77). Any of the above described CPPs may be used as cell penetrating peptide, i.e. as component a), in the complex according to the present invention. In particular, the component a), i.e. the CPP, in the complex according to the present invention may comprise the minimal domain of TAT, having the amino acid sequence YGRKKRRQRRR (SEQ ID NO: 2). In particular, the component a), i.e. the CPP, in the complex according to the present invention may comprise Penetratin having the amino acid sequence RQIKIYFQNRRMKWKK (SEQ ID NO: 1).

[0042] Various CPPs, which can be used as cell penetrating peptide, i.e. as component a), in the complex according to the present invention, are also disclosed in the review: Milletti, F., Cell-penetrating peptides: classes, origin, and current landscape. Drug Discov Today 17 (15-16): 850-60, 2012. In other words, the CPPs disclosed in Milletti, F., 2012, Cell-penetrating peptides: classes, origin, and current landscape. Drug Discov Today 17 (15-16): 850-60 can be used as cell penetrating peptide, i.e. as component a), in the complex according to the present invention.

[0043] Preferably, the cell penetrating peptide, which is comprised by the complex according to the present invention, [0044] i) has a length of the amino acid sequence of said peptide of 5 to 50 amino acids in total, preferably of 10 to 45 amino acids in total, more preferably of 15 to 45 amino acids in total; and/or [0045] ii) has an amino acid sequence comprising a fragment of the minimal domain of ZEBRA, said minimal domain extending from residue 170 to residue 220 of the ZEBRA amino acid sequence according to SEQ ID NO: 3, wherein, optionally, 1, 2, 3, 4, or 5 amino acids have been substituted, deleted, and/or added without abrogating said peptide's cell penetrating ability, or a sequence variant of such a fragment.

[0046] Thereby, it is preferred that the cell penetrating peptide, which is comprised by the complex according to the present invention, [0047] i) has a length of the amino acid sequence of said peptide of 5 to 50 amino acids in total, preferably of 10 to 45 amino acids in total, more preferably of 15 to 45 amino acids in total; and [0048] ii) has an amino acid sequence comprising a fragment of the minimal domain of ZEBRA, said minimal domain extending from residue 170 to residue 220 of the ZEBRA amino acid sequence according to SEQ ID NO: 3, wherein, optionally, 1, 2, 3, 4, or 5 amino acids have been substituted, deleted, and/or added without abrogating said peptide's cell penetrating ability, or a sequence variant of such a fragment.

[0049] Such preferred CPPs are disclosed in WO 2014/041505.

[0050] The term "ZEBRA" (also known as Zta, Z, EB1, or BZLF1) generally means the basic-leucine zipper (bZIP) transcriptional activator of the Epstein-Barr virus (EBV). The minimal domain of ZEBRA, which exhibits cell penetrating properties, has been identified as spanning from residue 170 to residue 220 of ZEBRA. The amino acid sequence of ZEBRA is disclosed under NCBI accession number YP_401673 and comprises 245 amino acids represented in SEQ ID NO: 3:

[0051] MMDPNSTSEDVKFTPDPYQVPFVQAFDQATRVYQDLGGPSQAPLPCVLWPVLPEPLPQGQL TAYHVSTAPTGSWFSAPQPAPENAYQAYAAPQLFPVSDITQNQQTNQAGGEAPQPGDNST VQTAAAVVFACPGANQGQQLADIGVPQPAPVAAPARRTRKPQQPESLEECDSELEIKRYKNR VASRKCRAKFKQLLQHYREVAAAKSSENDRLRLLLKQMCPSLDVDSIIPRTPDVLHEDLLNF (SEQ ID NO: 3--ZEBRA amino acid sequence (natural sequence from Epstein-Barr virus (EBV)) (YP_401673))

[0052] Recently, a CPP derived from the viral protein ZEBRA was described to transduce protein cargoes across biological membranes by both (i) direct translocation and (ii) lipid raft-mediated endocytosis (Rothe R, Liguori L, Villegas-Mendez A, Marques B, Grunwald D, Drouet E, et al. Characterization of the cell-penetrating properties of the Epstein-Barr virus ZEBRA trans-activator. The Journal of biological chemistry 2010; 285(26):20224-33). The present inventors assume that these two mechanisms of entry should promote both MHC class I and II restricted presentation of cargo antigens to CD8.sup.+ and CD4.sup.+ T cells, respectively. Accordingly, such a CPP can deliver multi-epitopic peptides to dendritic cells (DCs), and subsequently to promote CTL and Th cell activation and anti-tumor function. Such a CPP can thus efficiently deliver the complex according to the present invention to antigen presenting cells (APCs) and lead to multi-epitopic MHC class I and II restricted presentation.

[0053] In the context of the present invention, the term "MHC class I" designates one of the two primary classes of the Major Histocompatibility Complex molecules. The MHC class I (also noted "MHC I") molecules are found on every nucleated cell of the body. The function of MHC class I is to display an epitope to cytotoxic cells (CTLs). In humans, MHC class I molecules consist of two polypeptide chains, .alpha.- and .beta.2-microglobulin (b2m). Only the .alpha. chain is polymorphic and encoded by a HLA gene, while the b2m subunit is not polymorphic and encoded by the Beta-2 microglobulin gene. In the context of the present invention, the term "MHC class II" designates the other primary class of the Major Histocompatibility Complex molecules. The MHC class II (also noted "MHC II") molecules are found only on a few specialized cell types, including macrophages, dendritic cells and B cells, all of which are dedicated antigen-presenting cells (APCs).

[0054] Preferably, the sequence variant of a fragment of the minimal domain of ZEBRA as described above shares, in particular over the whole length, at least 70%, at least 75%, preferably at least 80%, more preferably at least 85%, even more preferably at least 90%, particularly preferably at least 95%, most preferably at least 99% amino acid sequence identity with the fragment of the minimal domain of ZEBRA as described above without abrogating the cell penetrating ability of the cell penetrating peptide. In particular, a "fragment" of the minimal domain of ZEBRA as defined above is preferably to be understood as a truncated sequence thereof, i.e. an amino acid sequence, which is N-terminally, C-terminally and/or intrasequentially truncated compared to the amino acid sequence of the native sequence. Moreover, such a "fragment" of the minimal domain of ZEBRA has preferably a length of 5 to 50 amino acids in total, preferably of 10 to 45 amino acids in total, more preferably of 15 to 45 amino acids in total.

[0055] Accordingly, the term "sequence variant" as used in the context of the present invention, i.e. throughout the present application, refers to any alteration in a reference sequence. The term "sequence variant" includes nucleotide sequence variants and amino acid sequence variants. Preferably, a reference sequence is any of the sequences listed in the "Table of Sequences and SEQ ID Numbers" (Sequence listing), i.e. SEQ ID NO: 1 to SEQ ID NO: 79. Preferably, a sequence variant shares, in particular over the whole length of the sequence, at least 70%, at least 75%, preferably at least 80%, more preferably at least 85%, even more preferably at least 90%, particularly preferably at least 95%, most preferably at least 99% sequence identity with a reference sequence, whereby sequence identity is calculated as described below. In particular, a sequence variant preserves the specific function of the reference sequence. Sequence identity is calculated as described below. In particular, an amino acid sequence variant has an altered sequence in which one or more of the amino acids in the reference sequence is deleted or substituted, or one or more amino acids are inserted into the sequence of the reference amino acid sequence. As a result of the alterations, the amino acid sequence variant has an amino acid sequence which is at least 70%, at least 75%, preferably at least 80%, more preferably at least 85%, even more preferably at least 90%, particularly preferably at least 95%, most preferably at least 99% identical to the reference sequence. For example, variant sequences which are at least 90% identical have no more than 10 alterations, i.e. any combination of deletions, insertions or substitutions, per 100 amino acids of the reference sequence.

[0056] In the context of the present invention, an amino acid sequence "sharing a sequence identity" of at least, for example, 95% to a query amino acid sequence of the present invention, is intended to mean that the sequence of the subject amino acid sequence is identical to the query sequence except that the subject amino acid sequence may include up to five amino acid alterations per each 100 amino acids of the query amino acid sequence. In other words, to obtain an amino acid sequence having a sequence of at least 95% identity to a query amino acid sequence, up to 5% (5 of 100) of the amino acid residues in the subject sequence may be inserted or substituted with another amino acid or deleted, preferably within the above definitions of variants or fragments. The same, of course, also applies similarly to nucleic acid sequences.

[0057] For (amino acid or nucleic acid) sequences without exact correspondence, a "% identity" of a first sequence may be determined with respect to a second sequence. In general, these two sequences to be compared are aligned to give a maximum correlation between the sequences. This may include inserting "gaps" in either one or both sequences, to enhance the degree of alignment. A % identity may then be determined over the whole length of each of the sequences being compared (so-called global alignment), that is particularly suitable for sequences of the same or similar length, or over shorter, defined lengths (so-called local alignment), that is more suitable for sequences of unequal length.

[0058] Methods for comparing the identity and homology of two or more sequences are well known in the art. The percentage to which two sequences are identical can e.g. be determined using a mathematical algorithm. A preferred, but not limiting, example of a mathematical algorithm which can be used is the algorithm of Karlin et al. (1993), PNAS USA, 90:5873-5877. Such an algorithm is integrated in the BLAST family of programs, e.g. BLAST or NBLAST program (see also Altschul et al., 1990, J. Mol. Biol. 215, 403-410 or Altschul et al. (1997), Nucleic Acids Res, 25:3389-3402), accessible through the home page of the NCBI at world wide web site ncbi.nlm.nih.gov) and FASTA (Pearson (1990), Methods Enzymol. 183, 63-98; Pearson and Lipman (1988), Proc. Natl. Acad. Sci. U.S.A 85, 2444-2448.). Sequences which are identical to other sequences to a certain extent can be identified by these programmes. Furthermore, programs available in the Wisconsin Sequence Analysis Package, version 9.1 (Devereux et al., 1984, Nucleic Acids Res., 387-395), for example the programs BESTFIT and GAP, may be used to determine the % identity between two polynucleotides and the identity and the % homology or identity between two polypeptide sequences. BESTFIT uses the "local homology" algorithm of (Smith and Waterman (1981), J. Mol. Biol. 147, 195-197.) and finds the best single region of similarity between two sequences.

[0059] More preferably, the fragments of the cell penetrating peptide according to the invention or the variants thereof as described above further retain said peptide's ability to present a cargo molecule such as antigens or antigenic epitopes at the surface of a cell, such as an antigen-presenting cell, in the context of MHC class I and/or MHC class II molecules. The ability of a cell penetrating peptide or complex comprising said cell penetrating peptide to present a cargo molecule such as antigens or antigenic epitopes at the surface of a cell in the context of MHC class I and/or MHC class II molecules can be checked by standard methods known to one skilled in the art, including capacity to stimulate proliferation and/or function of MHC-restricted CD4.sup.+ or CD8.sup.+ T cells with specificity for these epitopes.

[0060] The preferred cell penetrating peptide, which [0061] i) has a length of the amino acid sequence of said peptide of 5 to 50 amino acids in total, preferably of 10 to 45 amino acids in total, more preferably of 15 to 45 amino acids in total; and/or [0062] ii) has an amino acid sequence comprising a fragment of the minimal domain of ZEBRA, said minimal domain extending from residue 170 to residue 220 of the ZEBRA amino acid sequence according to SEQ ID NO: 3, wherein, optionally, 1, 2, 3, 4, or 5 amino acids have been substituted, deleted, and/or added without abrogating said peptide's cell penetrating ability, or a variant of such a fragment

[0063] preferably comprises an amino acid sequence having at least one conservatively substituted amino acid compared to the referenced sequence, meaning that a given amino acid residue is replaced by a residue having similar physiochemical characteristics.

[0064] Generally, substitutions for one or more amino acids present in the referenced amino acid sequence should be made conservatively. Examples of conservative substitutions include substitution of one aliphatic residue for another, such as Ile, Val, Leu, or Ala for one another, or substitutions of one polar residue for another, such as between Lys and Arg; Glu and Asp; or Gln and Asn. Other such conservative substitutions, for example, substitutions of entire regions having similar hydrophobicity properties, are well known (Kyte and Doolittle, 1982, J. Mol. Biol. 157(1):105-132). Substitutions of one or more L-amino acids with one or more D-amino acids are to be considered as conservative substitutions in the context of the present invention. Exemplary amino acid substitutions are presented in Table 1 below:

TABLE-US-00001 TABLE 1 Original residues Examples of substitutions Ala (A) Val, Leu, Ile, Gly Arg (R) His, Lys Asn (N) Gln Asp (D) Glu Cys (C) Ser Gln (Q) Asn Glu (E) Asp Gly (G) Pro, Ala His (H) Lys, Arg Ile (I) Leu, Val, Met, Ala, Phe Leu (L) Ile, Val, Met, Ala, Phe Lys (K) Arg, His Met (M) Leu, Ile, Phe Phe (F) Leu, Val, Ile, Tyr, Trp, Met Pro (P) Ala, Gly Ser (S) Thr Thr (T) Ser Trp (W) Tyr, Phe Tyr (Y) Trp, Phe Val (V) Ile, Met, Leu, Phe, Ala

[0065] Particularly preferably, the preferred cell penetrating peptide, which [0066] i) has a length of the amino acid sequence of said peptide of 5 to 50 amino acids in total, preferably of 10 to 45 amino acids in total, more preferably of 15 to 45 amino acids in total; and/or [0067] ii) has an amino acid sequence comprising a fragment of the minimal domain of ZEBRA, said minimal domain extending from residue 170 to residue 220 of the ZEBRA amino acid sequence according to SEQ ID NO: 3, wherein, optionally, 1, 2, 3, 4, or 5 amino acids have been substituted, deleted, and/or added without abrogating said peptide's cell penetrating ability, or a variant of such a fragment

[0068] comprises a Cys (C) substituted into a Ser (S), at the equivalent of position 189 relative to ZEBRA amino acid sequence of SEQ ID NO: 3.

[0069] Thereby, it is preferred that such a preferred cell penetrating peptide has an amino acid sequence comprising a sequence according to the following general formula (I):

[0070] with 0, 1, 2, 3, 4, or 5 amino acids which are substituted, deleted, and/or added without abrogating said peptide's cell penetrating ability, wherein [0071] X.sub.1 is K, R, or H, preferably X.sub.1 is K or R; [0072] X.sub.2 is R, K, or H, preferably X.sub.2 is R or K; [0073] X.sub.3 is Y, W, or F, preferably X.sub.3 is Y, W, or F; [0074] X.sub.4 is K, R, or H, preferably X.sub.4 is K or R; [0075] X.sub.5 is N or Q; [0076] X.sub.6 is R, K, or H, preferably X.sub.6 is R or K; [0077] X.sub.7 is V, I, M, L, F, or A, preferably X7 is V, I, M or L; [0078] X.sub.8 is A, V, L, I, or G, preferably X.sub.8 is A or G; [0079] X.sub.9 is S or T; [0080] X.sub.10 is R, K, or H, preferably X.sub.10 is R or K; [0081] X.sub.11 is K, R, or H, preferably X.sub.11 is K or R; [0082] X.sub.13 is R, K, or H, preferably X.sub.13 is R or K; [0083] X.sub.14 is A, V, L, I, or G, preferably X.sub.14 is A or G; [0084] X.sub.15 is K, R, or H, preferably X.sub.15 is K or R; [0085] X.sub.16 is F, L, V, I, Y, W, or M, preferably X.sub.16 is F, Y or W; and [0086] X.sub.17 is K, R, or H, preferably X.sub.17 is K or R.

[0087] Preferably, such a peptide, polypeptide or protein is either (entirely) composed of L-amino acids or (entirely) of D-amino acids, thereby forming "retro-inverso peptide sequences".

(2072, PLoS ONE 7(4): e35187) and listed in http://crdd.osdd.net/raghava/tumorhope/general.php?

[0118] Preferably, the cell penetrating peptide according to the invention is linked to an antigen or antigenic epitope and facilitates the cellular internalization of said antigen or antigenic epitope.

[0119] The complex according to the present invention may comprise one single cell penetrating peptide or more than one cell penetrating peptides. Preferably, the complex according to the present invention comprises no more than five cell penetrating peptides, more preferably the complex according to the present invention comprises no more than four cell penetrating peptides, even more preferably the complex according to the present invention comprises no more than three cell penetrating peptides, particularly preferably the complex according to the present invention comprises no more than two cell penetrating peptides and most preferably the complex according to the present invention comprises one single cell penetrating peptide.

[0120] Component b)--Antigen/Antigenic Epitope

[0121] The complex according to the present invention comprises as component b) at least one antigen or antigenic epitope.

[0122] As used herein, an "antigen" is any structural substance which serves as a target for the receptors of an adaptive immune response, in particular as a target for antibodies, T cell receptors, and/or B cell receptors. An "epitope", also known as "antigenic determinant", is the part (or fragment) of an antigen that is recognized by the immune system, in particular by antibodies, T cell receptors, and/or B cell receptors. Thus, one antigen has at least one epitope, i.e. a single antigen has one or more epitopes. In the context of the present invention, the term "epitope" is mainly used to designate T cell epitopes, which are presented on the surface of an antigen-presenting cell, where they are bound to Major Histocompatibility Complex (MHC). T cell epitopes presented by MHC class I molecules are typically, but not exclusively, peptides between 8 and 11 amino acids in length, whereas MHC class II molecules present longer peptides, generally, but not exclusively, between 12 and 25 amino acids in length.

[0123] Preferably, in the complex according to the present invention, the at least one antigen or antigenic epitope is selected from the group consisting of: (i) a peptide, a polypeptide, or a protein, (ii) a polysaccharide, (iii) a lipid, (iv) a lipoprotein or a lipopeptide, (v) a glycolipid, (vi) a nucleic acid, and (vii) a small molecule drug or a toxin. Thus, the at least one antigen or antigenic epitope may be a peptide, a protein, a polysaccharide, a lipid, a combination thereof including lipoproteins and glycolipids, a nucleic acid (e.g. DNA, siRNA, shRNA, antisense oligonucleotides, decoy DNA, plasmid), or a small molecule drug (e.g. cyclosporine A, paclitaxel, doxorubicin, methotrexate, 5-aminolevulinic acid), or any combination thereof in particular if more than one antigen or antigenic epitope is comprised by the inventive complex.

[0124] It is understood that the at least one antigen or antigenic epitope can comprise for example at least one, i.e. one or more, peptides, polypeptides or proteins linked together and/or at least one, i.e. one or more, nucleic acids, e.g. where each one encodes one peptide or polypeptide. Also the at least one antigen or antigenic epitope can be a combination of a protein, a lipid, and/or a polysaccharide including lipoproteins and glycolipids. Thus, in particular if the complex according to the present invention comprises more than one antigen or antigenic epitope, it can comprise more than one peptide, polypeptide, or protein, more than one polysaccharide, more than one lipid, more than one lipoprotein, more than one glycolipid, more than one nucleic acid, more than one small molecule drug or toxin, or a combination thereof.

[0125] Preferably, the complex according to the invention comprises at least one antigen or antigenic epitope comprising one or more epitope(s) from a cancer/tumor-associated antigen, a cancer/tumor-specific antigen, and/or an antigenic protein from a pathogen, including viral, bacterial, fungal, protozoal and multicellular parasitic antigenic protein.

[0126] More preferably, the at least one antigen or antigenic epitope comprises or consists of (i) at least one pathogen epitope and/or (ii) at least one cancer/tumor epitope, in particular at least one tumor epitope. Most preferably, the at least one antigen or antigenic epitope comprises or consists of at least one cancer/tumor epitope, in particular at least one tumor epitope.

[0127] It is particularly preferred that the complex according to the present invention comprises only such antigen(s) or antigenic epitope(s), which are cancer/tumor-associated antigen(s), cancer/tumor-specific antigen(s) and/or cancer/tumor epitope(s); in particular, which are tumor-associated antigen(s), tumor-specific antigen(s), and/or tumor epitope(s).

[0128] As used herein, "cancer epitope" means an epitope from a cancer-associated antigen or from a cancer-specific antigen. Accordingly, "tumor epitope" means an epitope from a tumor-associated antigen or from a tumor-specific antigen. Such epitopes are typically specific (or associated) for a certain kind of cancer/tumor. For instance, cancer/tumor epitopes include glioma epitopes. In particular, cancer/tumor-associated (also cancer/tumor-related) antigens are antigens, which are expressed by both, cancer/tumor cells and normal cells. Accordingly, those antigens are normally present since birth (or even before). Accordingly, there is a chance that the immune system developed self-tolerance to those antigens. Cancer/tumor-specific antigens, in contrast, are antigens, which are expressed specifically by cancer/tumor cells, but not by normal cells. Cancer/tumor-specific antigens include in particular neoantigens. In general neoantigens are antigens, which were not present before and are, thus, "new" to the immune system. Neoantigens are typically due to somatic mutations. In the context of cancer/tumors, cancer/tumor-specific neoantigens were typically not present before the cancer/tumor developed and cancer/tumor-specific neoantigens are usually encoded by somatic gene mutations in the cancerous cells/tumor cells. Since neoantigens are new to the immune system, the risk of self-tolerance of those antigens is considerably lower as compared to cancer/tumor-associated antigens. However, every cancer's set of tumor-specific mutations appears to be unique. Accordingly, in the context of the present invention it is preferred that such cancer/tumor-specific antigens, in particular neoantigens, are identified in a subject diagnosed with a cancer by methods known to the skilled person, e.g., cancer genome sequencing. After identification, the respective cancer/tumor-specific neoantigens and/or cancer/tumor-specific neoantigenic epitopes are used in a complex according to the present invention.

[0129] Preferably, a complex according to the present invention comprises one or more cancer/tumor-associated epitopes and/or one or more cancer/tumor-associated antigens (but preferably no cancer/tumor-specific epitopes). It is also preferred that a complex according to the present invention comprises one or more cancer/tumor-specific epitopes and/or one or more cancer/tumor-specific antigens (but preferably no cancer/tumor-associated epitopes). A complex according to the present invention may also preferably comprise both, (i) one or more cancer/tumor-associated epitopes and/or one or more cancer/tumor-associated antigens and (ii) one or more cancer/tumor-specific epitopes and/or one or more cancer/tumor-specific antigens.

[0130] Suitable cancer/tumor epitopes can be retrieved for example from cancer/tumor epitope databases, e.g. from van der Bruggen P, Stroobant V, Vigneron N, Van den Eynde B. Peptide database: T cell-defined tumor antigens. Cancer Immun 2013; URL: http://www.cancerimmunity.org/peptide/, wherein human tumor antigens recognized by CD4+ or CD8+ T cells are classified into four major groups on the basis of their expression pattern, or from the database "Tantigen" (TANTIGEN version 1.0, Dec. 1, 2009; developed by Bioinformatics Core at Cancer Vaccine Center, Dana-Farber Cancer Institute; URL: http://cvc.dfci.harvard.edu/tadb/). Examples of cancer/tumor epitopes include e.g. TRP2-derived epitopes, glycoprotein 100 (gp100) melanoma antigen-derived epitopes, glycoprotein 70 (gp70) antigen-derived epitopes, survivin epitopes, IEa epitopes, IL13r.alpha.2, Epha2 (ephrin type-A receptor 2), immunogenic fragments thereof, and fusions of such antigens and/or fragments. Furthermore, examples of cancer/tumor epitopes include epitopes of neoantigens, such as, for example, a neoantigen from MC-38 tumor cell line as described by Yadav et al. Nature. 2014 Nov. 27; 515(7528):572-6. As described above, neoantigens are antigens, which are entirely absent from the normal human genome. As compared with nonmutated self-antigens, neoantigens are of relevance to tumor control, as the quality of the T cell pool that is available for these antigens is not affected by central T cell tolerance. In particular, neoantigens may be based on individual tumor genomes. Potential neoantigens may be predicted by methods known to the skilled person, such as cancer genome sequencing or deep-sequencing technologies identifying mutations within the protein-coding part of the (cancer) genome.

Numerous other cancer antigens are well known in the art.

[0132] Preferably, the cancer/tumor antigen or the cancer/tumor epitope is a recombinant cancer/tumor antigen or a recombinant cancer/tumor epitope. Such a recombinant cancer/tumor antigen or a recombinant cancer/tumor epitope may be designed by introducing mutations that change (add, delete or substitute) particular amino acids in the overall amino acid sequence of the native cancer/tumor antigen or the native cancer/tumor epitope. The introduction of mutations does not alter the cancer/tumor antigen or the cancer/tumor epitope so much that it cannot be universally applied across a mammalian subject, and preferably a human or dog subject, but changes it enough that the resulting amino acid sequence breaks tolerance or is considered a foreign antigen in order to generate an immune response. Another manner may be creating a consensus recombinant cancer/tumor antigen or cancer/tumor epitope that has at least 85% and up to 99% amino acid sequence identity to its' corresponding native cancer/tumor antigen or native cancer/tumor epitope; preferably at least 90% and up to 98% sequence identity; more preferably at least 93% and up to 98% sequence identity; or even more preferably at least 95% and up to 98% sequence identity. In some instances the recombinant cancer/tumor antigen or the recombinant cancer/tumor epitope has 95%, 96%, 97%, 98%, or 99% amino acid sequence identity to its' corresponding native cancer/tumor antigen or cancer/tumor epitope. The native cancer/tumor antigen is the antigen normally associated with the particular cancer or cancer tumor. Depending upon the cancer/tumor antigen, the consensus sequence of the cancer/tumor antigen can be across mammalian species or within subtypes of a species or across viral strains or serotypes. Some cancer/tumor antigen do not vary greatly from the wild type amino acid sequence of the cancer/tumor antigen. The aforementioned approaches can be combined so that the final recombinant cancer/tumor antigen or cancer/tumor epitope has a percent similarity to native cancer antigen amino acid sequence as discussed above. Preferably, however, the amino acid sequence of an epitope of a cancer/tumor antigen as described herein is not mutated and, thus, identical to the reference epitope sequence.

[0133] As used herein "pathogen epitope" means an epitope from an antigenic protein, an antigenic polysaccharide, an antigenic lipid, an antigenic lipoprotein or an antigenic glycolipid from a pathogen including viruses, bacteria, fungi, protozoa and multicellular parasites. Antigenic proteins, polysaccharides, lipids, lipoproteins or glycolipids from pathogens include, herewith, proteins, polysaccharides, lipids, lipoproteins and glycolipids, respectively, from pathogens responsible of diseases which can be a target for vaccination including, for instance, Amoebiasis, Anthrax, Buruli Ulcer (Mycobacterium ulcerans), Caliciviruses associated diarrhoea, Campylobacter diarrhoea, Cervical Cancer (Human papillomavirus), Chlamydia trachomatis associated genital diseases, Cholera, Crimean-Congo haemorrhagic fever, Dengue Fever, Diptheria, Ebola haemorrhagic fever, Enterotoxigenic Escherichia coli (ETEC) diarrhoea, Gastric Cancer (Helicobacter pylori), Gonorrhea, Group A Streptococcus associated diseases, Group B Streptococcus associated diseases, Haemophilus influenzae B pneumonia and invasive disease, Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis E diarrhoea, Herpes simplex type 2 genital ulcers, HIV/AIDS, Hookworm Disease, Influenza, Japanese encephalitis, Lassa Fever, Leishmaniasis, Leptospirosi, Liver cancer (Hepatitis B), Liver Cancer (Hepatitis C), Lyme Disease, Malaria, Marburg haemorrhagic fever, Measles, Mumps, Nasopharyngeal cancer (Epstein-Barr virus), Neisseria meningitidis Meningitis, Parainfluenza associated pneumonia, Pertussis, Plague, Poliomyelitis, Rabies, Respiratory syncytial virus (RSV) pneumonia, Rift Valley fever, Rotavirus diarrhoea, Rubella, Schistosomiasis, Severe Acute Respiratory Syndrome (SARS), Shigellosis, Smallpox, Staphylococcus aureus associated diseases, Stomach Cancer (Helicobacter pylori), Streptococcus pneumoniae and invasive disease, Tetanus, Tick-borne encephalitis, Trachoma, Tuberculosis, Tularaemia, Typhoid fever, West-Nile virus associated disease, Yellow fever.

[0134] Preferably, the at least one antigen or antigenic epitope will be presented at the cell surface in an MHC class I and/or MHC class II context and/or in a CD1 context, whereby presentation at the cell surface in an MHC class I and/or MHC class II context is preferred. The phrase "epitope presentation in the MHC class I context" refers in particular to a CD8.sup.+ epitope lying in the groove of a MHC class I molecule at the surface of a cell. The phrase "epitope presentation in the MHC class II context" refers in particular to a CD4.sup.+ epitope lying in the groove of a MHC class II molecule at the surface of a cell. The phrase "epitope presentation in the CD1 context" refers in particular to a lipidic epitope lying in the groove of a cluster of differentiation 1 molecule at the surface of a cell.

[0135] Advantageously, the complex according to the invention comprises a cell penetrating peptide and at least one antigen or antigenic epitope, and allows the transport and presentation of said epitopes at the cell surface of antigen presenting cells in an MHC class I and MHC class II context, and is, thus, useful in vaccination and immunotherapy.

[0136] Preferably, the complex according to the present invention comprises at least one antigen or antigenic epitope, which is at least one CD4.sup.+ epitope and/or at least one CD8.sup.+ epitope.

[0137] The terms "CD4.sup.+ epitope" or "CD4.sup.+-restricted epitope", as used herein, designate an epitope recognized by a CD4.sup.+ T cell, said epitope in particular consisting of an antigen fragment lying in the groove of a MHC class II molecule. A single CD4.sup.+ epitope comprised in the complex according to the present invention preferably consists of about 12-25 amino acids. It can also consist of, for example, about 8-25 amino acids or about 6-100 amino acids.

[0138] The terms "CD8.sup.+ epitope" or "CD8+-restricted epitope", as used herein, designate an epitope recognized by a CD8.sup.+ T cell, said epitope in particular consisting of an antigen fragment lying in the groove of a MHC class I molecule. A single CD8.sup.+ epitope comprised in the complex according to the present invention preferably consists of about 8-11 amino acids. It can also consist of, for example, about 8-15 amino acids or about 6-100 amino acids.

[0139] Preferably, the at least one antigen can comprise or the at least one antigenic epitope can consist of a CD4.sup.+ epitope and/or a CD8.sup.+ epitope corresponding to antigenic determinant(s) of a cancer/tumor-associated antigen, a cancer/tumor-specific antigen, or an antigenic protein from a pathogen. More preferably, the at least one antigen can comprise or the at least one antigenic epitope can consist of a CD4.sup.+ epitope and/or a CD8.sup.+ epitope corresponding to antigenic determinant(s) of a cancer/tumor-associated antigen or a cancer/tumor-specific antigen. Most preferably, the at least one antigen can comprise or the at least one antigenic epitope can consist of a CD4.sup.+ epitope and/or a CD8.sup.+ epitope corresponding to antigenic determinant(s) of a tumor-associated antigen or a tumor-specific antigen.

[0140] It is also preferred that the complex according to the present invention comprises at least two antigens or antigenic epitopes, wherein at least one antigen or antigenic epitope comprises or consists a CD4.sup.+ epitope and at least one antigen or antigenic epitope comprises or consists a CD8.sup.+ epitope. It is now established that T.sub.h cells (CD4.sup.+) play a central role in the anti-tumor immune response both in DC licensing and in the recruitment and maintenance of CTLs (CD8.sup.+) at the tumor site. Therefore, a complex according to the present invention comprising at least two antigens or antigenic epitopes, wherein at least one antigen or antigenic epitope comprises or consists of a CD4.sup.+ epitope and at least one antigen or antigenic epitope comprises or consists a CD8.sup.+ epitope, provides an integrated immune response allowing simultaneous priming of CTLs and Th cells and is thus preferable to immunity against only one CD8.sup.+ epitope or only one CD4.sup.+ epitope. For example, the complex according to the present invention may preferably comprise an Ealpha-CD4.sup.+ epitope and a gp100-CD8+ epitope.

[0141] Preferably, the complex according to the present invention comprises at least two antigens or antigenic epitopes, wherein the at least two antigens or antigenic epitopes comprise or consist of at least two, e.g. 2, 3, 4, 5, 6, 7, 8, 9, or more, CD4.sup.+ epitopes and/or at least two, e.g. 2, 3, 4, 5, 6, 7, 8, 9, or more, CD8.sup.+ epitopes. Thereby, the at least two antigens or antigenic epitopes are preferably different antigens or antigenic epitopes, more preferably the at least two antigens or antigenic epitopes are different from each other but relating to the same kind of tumor. A multi-antigenic vaccine will (i) avoid outgrowth of antigen-loss variants, (ii) target different tumor cells within a heterogeneous tumor mass and (iii) circumvent patient-to-patient tumor variability. Thus, the complex according to the present invention particularly preferably comprises at least four antigens or antigenic epitopes, in particular with at least two CD8.sup.+ epitopes and at least two CD4.sup.+ epitopes. Such a complex according to the present invention induces multi-epitopic CD8 CTLs and CD4 T.sub.h cells to function synergistically to counter tumor cells and promote efficient anti-tumor immunity. T.sub.h cells are also involved in the maintenance of long-lasting cellular immunity that was monitored after vaccination. Such a complex according to the present invention induces polyclonal, multi-epitopic immune responses and poly-functional CD8.sup.+ and CD4.sup.+ T cells, and thus efficacious anti-tumor activity.

[0142] Preferably, the complex according to the present invention comprises at least two antigens or antigenic epitopes, more preferably the complex according to the present invention comprises at least three antigens or antigenic epitopes, even more preferably the complex according to the present invention comprises at least four antigens or antigenic epitopes, particularly preferably the complex according to the present invention comprises at least five antigens or antigenic epitopes and most preferably the complex according to the present invention comprises at least six antigens or antigenic epitopes. The antigens or antigenic epitopes comprised by the complex according to the present invention may be the same or different, preferably the antigens or antigenic epitopes comprised by the complex according to the present invention are different from each other.

In such a case preferably different complexes according to the present invention comprise different subsets of all of said glioma epitopes, so that for example a vaccine according to the present invention comprising such different complexes according to the present invention comprises all of said glioma epitopes but distributed in the different complexes.

[0161] Moreover, a complex according to the invention may also comprise at least one antigen or antigenic epitope, wherein said antigen or antigenic epitope is a polysaccharide, a lipid, a lipoprotein, and/or a glycolipid, in particular a polysaccharidic, lipidic, lipoproteic, and/or glycolipidic epitope, which can be, for example, pathogen epitopes as defined herewith.

Rather, component a) and component c) are positioned in the complex for example before or after such a stretch of all antigens and/or antigenic epitopes. However, the antigens and/or antigenic epitopes positioned consecutively in such a way may be linked to each other for example by a spacer or linker as described below, which is neither component a), i.e. a cell penetrating peptide, nor component c), i.e. a TLR peptide agonist.

[0209] Transforming Growth Factor Beta Receptor 2 (TGF.beta.R2)

[0210] TGF.beta. receptors are single pass serine/threonine kinase receptors. They exist in several different isoforms. TGF.beta.R2 is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with another receptor protein, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of a subset of genes related to cell proliferation.

[0211] P53

[0212] P53 is a tumor suppressor protein having a role in preventing genome mutation. P53 has many mechanisms of anticancer function and plays a role in apoptosis, genomic stability, and inhibition of angiogenesis. In its anti-cancer role, p53 works through several mechanisms: it an activate DNA repair proteins when DNA has sustained damage; it can arrest growth by holding the cell cycle at the G1/S regulation point on DNA damage recognition; and it can initiate apoptosis.

[0213] Kirsten Ras (KRas)

[0214] GTPase KRas also known as V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog and KRAS, performs an essential function in normal tissue signaling, and the mutation of a KRAS gene is an essential step in the development of many cancers. Like other members of the ras subfamily, the KRAS protein is a GTPase and is an early player in many signal transduction pathways. KRAS is usually tethered to cell membranes because of the presence of an isoprene group on its C-terminus. The amino acid sequence of KRas is shown in the following:

OGT catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues of intracellular proteins. OGT is a part of a host of biological functions within the human body. OGT is involved in the resistance of insulin in muscle cells and adipocytes by inhibiting the Threonine 308 phosphorylation of AKT1, increasing the rate of IRS1 phosphorylation (at Serine 307 and Serine 632/635), reducing insulin signaling, and glycosylating components of insulin signals. Additionally, OGT catalyzes intracellular glycosylation of serine and threonine residues with the addition of N-acetylglucosamine. Studies show that OGT alleles are vital for embryogenesis, and that OGT is necessary for intracellular glycosylation and embryonic stem cell vitality. OGT also catalyzes the posttranslational modification that modifies transcription factors and RNA polymerase II, however the specific function of this modification is mostly unknown.

[0245] EphA2

[0246] Ephrins and their receptors (ephrin receptors, "Ephs") belong to a subfamily of proteins involved in crucial processes occurring during embryonic development of the central nervous system, including axon mapping, cell migration, and angiogenesis. Recent findings suggest that Eph/ephrin are overexpressed by glioma cells and their signaling affects glioma cell growth, migration, and invasion (Nakada, M., Y. Hayashi, and J. Hamada, Role of Eph/ephrin tyrosine kinase in malignant glioma. Neuro Oncol, 2011. 13(11): p. 1163-70). 16 ephrin receptors (Ephs) have been identified. The ephrin receptors are divided into two groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. EPH receptor A2 (ephrin type-A receptor 2) binds ephrin-A ligands. The amino acid sequence of EphA2 is shown in the following:

[0263] Neuroligin 4

[0264] Neuroligin (NLGN), a type I membrane protein, is a cell adhesion protein on the postsynaptic membrane that mediates the formation and maintenance of synapses between neurons. Neuroligins act as ligands for .beta.-Neurexins, which are cell adhesion proteins located presynaptically. Neuroligins also affect the properties of neural networks by specifying synaptic functions, and they mediate signalling by recruiting and stabilizing key synaptic components. Neuroligins interact with other postsynaptic proteins to localize neurotransmitter receptors and channels in the postsynaptic density as the cell matures. The amino acid sequence of neuroligin 4 is shown in the following:

[0507] Component c)--TLR Peptide Agonist

[0508] In the complex according to the present invention, the TLR peptide agonist allows an increased targeting of the vaccine towards dendritic cells along with self-adjuvancity. Physical linkage of a TLR peptide agonist to the CPP and the at least one antigen or antigenic epitope according to the present invention in the complex according to the present invention provides an enhanced immune response by simultaneous stimulation of antigen presenting cells, in particular dendritic cells, that internalize, metabolize and display antigen(s).

[0509] As used in the context of the present invention, a "TLR peptide agonist" is an agonist of a Toll-like receptor (TLR), i.e. it binds to a TLR and activates the TLR, in particular to produce a biological response. Moreover, the TLR peptide agonist is a peptide, a polypeptide or a protein as defined above. Preferably, the TLR peptide agonist comprises from 10 to 150 amino acids, more preferably from 15 to 130 amino acids, even more preferably from 20 to 120 amino acids, particularly preferably from 25 to 110 amino acids, and most preferably from 30 to 100 amino acids.

[0510] Toll like receptors (TLRs) are transmembrane proteins that are characterized by extracellular, transmembrane, and cytosolic domains. The extracellular domains containing leucine-rich repeats (LRRs) with horseshoe-like shapes are involved in recognition of common molecular patterns derived from diverse microbes. Toll like receptors include TLRs1-10. Compounds capable of activating TLR receptors and modifications and derivatives thereof are well documented in the art. TLR1 may be activated by bacterial lipoproteins and acetylated forms thereof, TLR2 may in addition be activated by Gram positive bacterial glycolipids, LPS, LP A, LTA, fimbriae, outer membrane proteins, heat shock proteins from bacteria or from the host, and Mycobacterial lipoarabinomannans. TLR3 may be activated by dsRNA, in particular of viral origin, or by the chemical compound poly(LC). TLR4 may be activated by Gram negative LPS, LTA, Heat shock proteins from the host or from bacterial origin, viral coat or envelope proteins, taxol or derivatives thereof, hyaluronan containing oligosaccharides and fibronectins. TLR5 may be activated with bacterial flagellae or flagellin. TLR6 may be activated by mycobacterial lipoproteins and group B streptococcus heat labile soluble factor (GBS-F) or staphylococcus modulins. TLR7 may be activated by imidazoquinolines. TLR9 may be activated by unmethylated CpG DNA or chromatin--IgG complexes.

[0511] Preferably, the TLR peptide agonist comprised by the complex according to the present invention is an agonist of TLR1, 2, 4, 5, 6, and/or 10. TLRs are expressed either on the cell surface (TLR1, 2, 4, 5, 6, and 10) or on membranes of intracellular organelles, such as endosomes (TLR3, 4, 7, 8, and 9). The natural ligands for the endosomal receptors turned out to be nucleic acid-based molecules (except for TLR4). The cell surface-expressed TLR1, 2, 4, 5, 6, and 10 recognize molecular patterns of extracellular microbes (Monie, T. P., Bryant, C. E., et al. 2009: Activating immunity: Lessons from the TLRs and NLRB. Trends Biochem. Sci. 34(11), 553-561). TLRs are expressed on several cell types but virtually all TLRs are expressed on DCs allowing these specialized cells to sense all possible pathogens and danger signals.

[0512] However, TLR2, 4, and 5 are constitutively expressed at the surface of DCs. Accordingly, the TLR peptide agonist comprised by the complex according to the present invention is more preferably a peptide agonist of TLR2, TLR4 and/or TLR5. Even more preferably, the TLR peptide agonist is a TLR2 peptide agonist and/or a TLR4 peptide agonist. Particularly preferably, the TLR peptide agonist is a TLR4 peptide agonist. Most preferably, the TLR peptide agonist is one TLR peptide agonist, which is both, a TLR2 and a TLR4 agonist. TLR2 can detect a wide variety of ligands derived from bacteria, viruses, parasites, and fungi. The ligand specificity is often determined by the interaction of TLR2 with other TLRs, such as TLR1, 6, or 10, or non-TLR molecules, such as dectin-1, CD14, or CD36. The formation of a heterodimer with TLR1 enables TLR2 to identify triacyl lipoproteins or lipopeptides from (myco)bacterial origin, such as Pam3CSK4 and peptidoglycan (PGA; Gay, N. J., and Gangloff, M. (2007): Structure and function of Toll receptors and their ligands. Annu. Rev. Biochem. 76, 141-165; Spohn, R., Buwitt-Beckmann, U., et al. (2004): Synthetic lipopeptide adjuvants and Toll-like receptor 2--Structure-activity relationships. Vaccine 22(19), 2494-2499).

[0513] Heterodimerization of TLR2 and 6 enables the detection of diacyl lipopeptides and zymosan. Lipopolysaccharide (LPS) and its derivatives are ligands for TLR4 and flagellin for TLR5 (Bryant, C. E., Spring, D. R., et al. (2010). The molecular basis of the host response to lipopolysaccharide. Nat. Rev. Microbiol. 8(1), 8-14).

[0514] TLR2 interacts with a broad and structurally diverse range of ligands, including molecules expressed by microbes and fungi. Multiple TLR2 agonists have been identified, including natural and synthetic lipopeptides (e.g. Mycoplasma fermentas macrophage-activating lipopeptide (MALP-2)), peptidoglycans (PG such as those from S. aureus), lipopolysaccharides from various bacterial strains (LPS), polysaccharides (e.g. zymosan), glycosylphosphatidyl-inositol-anchored structures from gram positive bacteria (e.g. lipoteichoic acid (LTA) and lipo-arabinomannan from mycobacteria and lipomannas from M. tuberculosis). Certain viral determinants may also trigger via TLR2 (Barbalat R, Lau L, Locksley R M, Barton G M. Toll-like receptor 2 on inflammatory monocytes induces type I interferon in response to viral but not bacterial ligands. Nat Immunol. 2009: 10(11):1200-7). Bacterial lipopeptides are structural components of cell walls. They consist of an acylated s-glycerylcysteine moiety to which a peptide can be conjugated via the cysteine residue. Examples of TLR2 agonists, which are bacterial lipopeptides, include MALP-2 and it's synthetic analogue di-palmitoyl-S-glyceryl cysteine (Pam.sub.2Cys) or tri-palmitoyl-S-glyceryl cysteine (Pam.sub.3Cys).

[0515] A diversity of ligands interact with TLR4, including Monophosphoryl Lipid A from Salmonella minnesota R595 (MPLA), lipopolysaccharides (LPS), mannans (Candida albicans), glycoinositolphospholipids (Trypanosoma), viral envelope proteins (RSV and MMTV) and endogenous antigens including fibrinogen and heat-shock proteins. Such agonists of TLR4 are for example described in Akira S, Uematsu S, Takeuchi O. Pathogen recognition and innate immunity. Cell. Feb. 24; 2006: 124(4):783-801 or in Kumar H, Kawai T, Akira S. Toll-like receptors and innate immunity. Biochem Biophys Res Commun. October 30; 2009 388(4):621-5. LPS, which is found in the outer membrane of gram negative bacteria, is the most widely studied of the TLR4 ligands. Suitable LPS-derived TLR4 agonist peptides are described for example in WO 2013/120073 (A1).

[0516] TLR5 is triggered by a region of the flagellin molecule expressed by nearly all motile bacteria. Thus, flagellin, or peptides or proteins derived from flagellin and/or variants or fragments of flagellin are also suitable as TLR peptide agonists comprised by the complex according to the present invention.

[0517] Examples of TLR peptide agonists thus include the TLR2 lipopeptide agonists MALP-2, Pam2Cys and Pam.sub.3Cys or modifications thereof, different forms of the TLR4 agonist LPS, e.g. N. meningitidis wild-type L3-LPS and mutant penta-acylated LpxL1-LPS, and the TLR5 agonist flagellin.

[0518] However, it is preferred that the TLR peptide agonist comprised by the complex according to the present invention is neither a lipopeptide nor a lipoprotein, neither a glycopeptide nor a glycoprotein, more preferably, the TLR peptide agonist comprised by the complex according to the present invention is a classical peptide, polypeptide or protein as defined herein.

[0519] A preferred TLR2 peptide agonist is annexin II or an immunomodulatory fragment thereof, which is described in detail in WO 2012/048190 A1 and US patent application 13/0331546, in particular a TLR2 peptide agonist comprising an amino acid sequence according to SEQ ID NO: 4 or SEQ ID NO: 7 of WO 2012/048190 A1 or fragments or variants thereof are preferred.

[0520] Thereby, a TLR2 peptide agonist comprising or consisting of an amino acid sequence according to SEQ ID NO: 15 or a sequence variant thereof as described above is particularly preferred as component c), i.e. as the at least one TLR peptide agonist, comprised by the complex according to the present invention.

TABLE-US-00026 (TLR2 peptide agonist Anaxa) SEQ ID NO: 15 STVHEILCKLSLEGDHSTPPSAYGSVKPYTNFDAE

[0521] Regarding TLR4, TLR peptides agonists are particularly preferred, which correspond to motifs that bind to TLR4, in particular (i) peptides mimicking the natural LPS ligand (RS01: Gln-Glu-Ile-Asn-Ser-Ser-Tyr and RS09: Ala-Pro-Pro-His-Ala-Leu-Ser) and (ii) Fibronectin derived peptides. The cellular glycoprotein Fibronectin (FN) has multiple isoforms generated from a single gene by alternative splicing of three exons. One of these isoforms is the extra domain A (EDA), which interacts with TLR4.

[0522] Further suitable TLR peptide agonists comprise a fibronectin EDA domain or a fragment or variant thereof. Such suitable fibronectin EDA domains or a fragments or variants thereof are disclosed in EP 1 913 954 B1, EP 2 476 440 A1, US 2009/0220532 A1, and WO 2011/101332 A1. Thereby, a TLR4 peptide agonist comprising or consisting of an amino acid sequence according to SEQ ID NO: 45 or a sequence variant thereof as described above is particularly preferred as component c), i.e. as the at least one TLR peptide agonist, comprised by the complex according to the present invention.

TABLE-US-00027 (TLR4 peptide agonist EDA) SEQ ID NO: 45 NIDRPKGLAFTDVDVDSIKIAWESPQGQVSRYRVTYSSPEDGIRELFPAP DGEDDTAELQGLRPGSEYTVSVVALHDDMESQPLIGIQST

[0523] In addition, high-mobility group box 1 protein (HMGB1) and peptide fragments thereof are assumed to be TLR4 agonists. Such HMGB1-derived peptides are for example disclosed in US 2011/0236406 A1.

[0524] The complex according to the present invention comprises at least one TLR peptide agonist, preferably the complex according to the present invention comprises more than one TLR peptide agonist, in particular 2, 3, 4, 5, 6, 7, 8, 9, 10 or more TLR peptide agonists, more preferably the complex according to the present invention comprises (at least) two or three TLR peptide agonists, even more preferably the complex according to the present invention comprises (at least) four or five TLR peptide agonists. If more than one TLR peptide agonist is comprised by the complex according to the present invention it is understood that said TLR peptide agonist is in particular also covalently linked in the complex according to the present invention, e.g. to another TLR peptide agonist and/or to a component a), i.e. a cell penetrating peptide, and/or to a component b), i.e. an antigen or antigenic epitope.

[0525] In a particularly preferred embodiment, the complex according to the present invention comprises one single TLR peptide agonist. In particularly, in this particularly preferred embodiment, the complex according to the present invention comprises one single TLR peptide agonist and no further component having TLR agonist properties except the one single TLR peptide agonist as described.

[0526] The various TLR peptide agonists comprised by the complex according to the present invention may be the same or different. Preferably, the various TLR peptide agonists comprised by the complex according to the present invention are different from each other.

[0527] Moreover, it is preferred that the more than one antigen or antigenic epitope, in particular 2, 3, 4, 5, 6, 7, 8, 9, 10 antigens or antigenic epitopes, or more TLR peptide agonists, in particular 2, 3, 4, 5, 6, 7, 8, 9, 10 TLR agonists, are positioned consecutively in the complex according to the present invention. This means in particular that all TLR peptide agonists comprised by the complex are positioned in a stretch, which is neither interrupted by component a), i.e. a cell penetrating peptide, nor by component b), i.e. at least one antigen or antigenic epitope. Rather, component a) and component b) are positioned in the complex for example before or after such a stretch of all TLR peptide agonists. However, the TLR peptide agonists positioned consecutively in such a way may be linked to each other for example by a spacer or linker as described below, which is neither component a), i.e. a cell penetrating peptide, nor component b), i.e. at least one antigen or antigenic epitope.

[0528] Alternatively, however, the various TLR peptide agonists may also be positioned in any other way in the complex according to the present invention, for example with component a) and/or component b) positioned in between two or more TLR peptide agonists, i.e. with one or more TLR peptide agonist positioned between component a) and component b) (or vice versa) and, optionally, one or more TLR peptide agonists positioned at the respective other end of component a) and/or component b).

[0529] It is understood that a number of different TLR peptide agonists activating the same or different TLR receptors may be advantageously comprised by a single complex according to the present invention. Alternatively, a number of different TLR peptide agonists activating the same or different TLR receptors may be distributed to subsets of different TLR peptide agonists activating the same or different TLR receptors, which are comprised by different complexes according to the present invention, whereby such different complexes comprising different subsets may advantageously be administered simultaneously, e.g. in a single vaccine, to a subject in need thereof.

[0530] Linkage of Components a), b), and c) in the Complex according to the Present Invention

[0531] In the complex according to the present invention, components a), b) and c) are covalently linked, i.e. the linkage between two out of the three components a), b), and c) of the complex according to the present invention is a covalent linkage. Preferably, two out of the three components a), b), and c) of the complex according to the present invention are covalently linked to each other (i.e. the "first" and the "second" component), and the third component out of the three components a), b), and c) is covalently linked either to the first component out of the three components a), b), and c) or to the second component out of the three components a), b), and c). Thereby, preferably a linear molecule is formed. However, it is also conceivable that each of the three components a), b), and c) is covalently linked to both of the other components out of the three components a), b), and c).

[0532] A "covalent linkage" (also covalent bond), as used in the context of the present invention, refers to a chemical bond that involves the sharing of electron pairs between atoms. A "covalent linkage" (also covalent bond) in particular involves a stable balance of attractive and repulsive forces between atoms when they share electrons. For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full outer shell, corresponding to a stable electronic configuration. Covalent bonding includes many kinds of interactions, including for example .sigma.-bonding, .pi.-bonding, metal-to-metal bonding, agostic interactions, and three-center two-electron bonds. Accordingly, the complex according to the present invention may also be referred to as "compound", in particular it may be referred to as "molecule".

[0533] Preferably, in the complex according to the present invention, components a), b), and c) are covalently linked by chemical coupling in any suitable manner known in the art, such as cross-linking methods. However, attention is drawn to the fact that many known chemical cross-linking methods are non-specific, i.e., they do not direct the point of coupling to any particular site on the components a), b), and c). Thus, the use of non-specific cross-linking agents may attack functional sites or sterically block active sites, rendering the fused components of the complex according to the present invention biologically inactive. It is referred to the knowledge of the skilled artisan to block potentially reactive groups by using appropriate protecting groups. Alternatively, the use of the powerful and versatile oxime and hydrazone ligation techniques, which are chemo-selective entities that can be applied for the cross-linking of components a), b), and c) may be employed. This linking technology is described e.g. by Rose et al. (1994), JACS 116, 30.

[0534] Coupling specificity can be increased by direct chemical coupling to a functional group found only once or a few times in components a), b), and/or c), which functional group is to be cross-linked to the another of the components a), b), and c). As an example, the cystein thiol group may be used, if just one cystein residue is present in a certain component a), b), or c) of complex according to the present invention. Also, for example, if a certain component a), b), or c) contains no lysine residues, a cross-linking reagent specific for primary amines will be selective for the amino terminus of the respective component. Alternatively, cross-linking may also be carried out via the side chain of a glutamic acid residue placed at the N-terminus of the peptide such that a amide bond can be generated through its side-chain. Therefore, it may be advantageous to link a glutamic acid residue to the N-terminus of a certain component a), b), or c). However, if a cysteine residue is to be introduced into a certain component a), b), or c), introduction at or near its N- or C-terminus is preferred. Conventional methods are available for such amino acid sequence alterations based on modifications of certain component a), b), or c) by either adding one or more additional amino acids, e.g. inter alia an cystein residue, to the translocation sequence or by substituting at least one residue of the translocation sequence(s) being comprised in the respective component. In case a cystein side chain is used for coupling purposes, a certain component a), b), or c) has preferably one cystein residue. Any second cystein residue should preferably be avoided and can, optionally, be replaced when they occur in the respective component comprised by the complex according to the present invention. When a cysteine residue is replaced in the original sequence of a certain component a), b), or c), it is typically desirable to minimize resulting changes in the peptide folding of the respective component. Changes in folding are minimized when the replacement is chemically and sterically similar to cysteine. Therefore, serine is preferred as a replacement for cystein.

[0535] Coupling of two out of the three components a), b), and c) can be accomplished via a coupling or conjugating agent including standard peptide synthesis coupling reagents such as HOBt, HBTU, DICI, TBTU. There are several intermolecular cross-linking agents which can be utilized, see for example, Means and Feeney, Chemical Modification of Proteins, Holden-Day, 1974, pp. 39-43. Among these reagents are, for example, N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP) or N,N'-(1,3-phenylene)bismaleimide; N,N'-ethylene-bis-(iodoacetamide) or other such reagent having 6 to 11 carbon methylene bridges; and 1,5-difluoro-2,4-dinitrobenzene. Other cross-linking agents useful for this purpose include: p,p'-difluoro-m,m'-dinitrodiphenylsulfone; dimethyl adipimidate; phenol-1,4-disulfonylchloride; hexamethylenediisocyanate or di isothiocyanate, or azophenyl-p-diisocyanate; glutaraldehyde and disdiazobenzidine. Cross-linking agents may be homobifunctional, i.e., having two functional groups that undergo the same reaction. A preferred homobifunctional cross-linking agent is bismaleimidohexane (BMH). BMH contains two maleimide functional groups, which react specifically with sulfhydryl-containing compounds under mild conditions (pH 6.5-7.7). The two maleimide groups are connected by a hydrocarbon chain. Therefore, BMH is useful for irreversible cross-linking of proteins (or polypeptides) that contain cysteine residues. Cross-linking agents may also be heterobifunctional. Heterobifunctional cross-linking agents have two different functional groups, for example an amine-reactive group and a thiol-reactive group, that will cross-link two proteins having free amines and thiols, respectively. Examples of heterobifunctional cross-linking agents are Succinimidyl-4-(N-maleimidomethyl)-cyclohexane-1-carboxylate (SMCC), m-maleimidobenzoyl-N-hydroxysuccinimide ester (MBS), and succinimide 4-(p-maleimidophenyl)butyrate (SMPB), an extended chain analog of MBS. The succinimidyl group of these cross-linkers reacts with a primary amine, and the thiol-reactive maleimide forms a covalent bond with the thiol of a cysteine residue. Because cross-linking agents often have low solubility in water, a hydrophilic moiety, such as a sulfonate group, may be added to the cross-linking agent to improve its water solubility. Sulfo-MBS and sulfo-SMCC are examples of cross-linking agents modified for water solubility. Many cross-linking agents yield a conjugate that is essentially non-cleavable under cellular conditions. Therefore, some cross-linking agents contain a covalent bond, such as a disulfide, that is cleavable under cellular conditions. For example, Traut's reagent, dithiobis (succinimidylpropionate) (DSP), and N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP) are well-known cleavable cross-linkers. The use of a cleavable cross-linking agent permits the cell penetrating peptide, the at least one antigen or antigenic epitope and the at least one TLR peptide agonist comprised by the complex according to the present invention to separate from each other after delivery into the target cell. For this purpose, direct disulfide linkage may also be useful. Chemical cross-linking may also include the use of spacer arms. Spacer arms provide intramolecular flexibility or adjust intramolecular distances between conjugated moieties and thereby may help preserve biological activity. A spacer arm may be in the form of a protein (or polypeptide) moiety that includes spacer amino acids, e.g. proline. Alternatively, a spacer arm may be part of the cross-linking agent, such as in "long-chain SPDP" (Pierce Chem. Co., Rockford, Ill., cat. No. 21651 H). Numerous cross-linking agents, including the ones discussed above, are commercially available. Detailed instructions for their use are readily available from the commercial suppliers. More detailed information on protein cross-linking and conjugate preparation, which is useful in the context of linkage of components a), b), and c) comprised by the complex according to the present invention can be retrieved from: Wong, Chemistry of Protein Conjugation and Cross-Linking, CRC Press (1991).

[0536] Cross-linking agents for peptide or protein crosslinking include for example (i) amine-to-amine crosslinkers, e.g. homobifunctional amine-specific protein crosslinking reagents based on NHS-ester and imidoester reactive groups for selective conjugation of primary amines; available in short, long, cleavable, irreversible, membrane permeable, and cell surface varieties; (ii) sulfhydryl-to-carbohydrate crosslinkers, e.g. crosslinking reagents based on maleimide and hydrazide reactive groups for conjugation and formation of covalent crosslinks; (iii) sulfhydryl-to-sulfhydryl crosslinkers, e.g. homobifunctional sulfhydryl-specific crosslinking reagents based on maleimide or pyridyldithiol reactive groups for selective covalent conjugation of protein and peptide thiols (reduced cysteines) to form stable thioether bonds; (iv) photoreactive crosslinkers, e.g. aryl azide, diazirine, and other photo-reactive (light-activated) chemical heterobifunctional crosslinking reagents to conjugate proteins, nucleic acids and other molecular structures involved in receptor-ligand interaction complexes via two-step activation; (v) amine-to-sulfhydryl crosslinkers, e.g. heterobifunctional protein crosslinking reagents for conjugation between primary amine (lysine) and sulfhydryl (cysteine) groups of proteins and other molecules; available with different lengths and types of spacer arms; and (vi) amine-to-amine crosslinkers, e.g. carboxyl-to-amine crosslinkers, e.g. Carbodiimide crosslinking reagents, DCC and EDC (EDAC), for conjugating carboxyl groups (glutamate, aspartate, C-termini) to primary amines (lysine, N-termini) and also N-hydroxysuccinimide (NHS) for stable activation of carboxylates for amine-conjugation.

[0537] Examples of crosslinkers in general, which can be used in the complex according to the present invention, include N-(.alpha.-Maleimidoacetoxy)-succinimide ester, N-5-Azido-2-nitrobenzyloxy-succinimide, 1,4-Bis-Maleimidobutane, 1,4-Bis-Maleimmidyl-2,3-dihydroxy-butane, Bis-Maleimidohexane, Bis-Maleimidoethane, N-(.beta.-Maleimidopropionic acid)hydrazide*TFA, N-(.beta.-Maleimidopropyloxy)succinimide ester, 1,8-Bis-Maleimidodiethylene-glycol, 1,11-Bis-Maleimidotriethyleneglycol, Bis (sulfosuccinimidyl)suberate, Bis (sulfosuccinimidyl)glutarate-d0, Bis (sulfosuccinimidyl)2,2,4,4-glutarate-d4, Bis (sulfosuccinimidyl)suberate-d0, Bis (sulfosuccinimidyl)2,2,7,7-suberate-d4, Bis (NHS)PEG5, Bis (NHS)PEG9, Bis (2-[succinimidoxycarbonyloxy]ethyl)sulfone, N,N-Dicyclohexylcarbodiimide, 1-5-Difluoro-2,4-dinitrobenzene, Dimethyl adipimidate*2HCl, Dimethyl pimelimidate*2HCl, Dimethyl suberimidate*2HCl, Disuccinimidyl glutarate, Dithiobis(succimidylpropionate) (Lomant's Reagent), Disuccinimidyl suberate, Disuccinimidyl tartarate, Dimethyl 3,3'-dithiobispropionimidate*2HCl, Dithiobis-maleimidoethane, 3,3'-Dithiobis (sulfosucci nimidylpropionate), 1-Ethyl-3-(3-dimethylami nopropyl) carbodi imide hydrochloride, Ethylene glycol bis (succi nimidylsuccinate), N-.epsilon.-Maleimidocaproic acid, N-(.epsilon.-Maleimidocaproic acid)hydrazide, N-(.epsilon.-Maleimidocaproyloxy)succinimide ester, N-(.gamma.-Maleimidobutyryloxy)succinimide ester, N-(.kappa.-Maleimidoundecanoic acid)hydrazide, NHS-LC-Diazirine, Succinimidyl 4-(N-maleimidomethyl) cyclohexane-1-carboxy-(6-amidocaproate, Succinimidyl 6-(3'-[2-pyridyldithio] propionamido)hexanoate, L-Photo-Leucine, L-Photo-Methionine, m-Maleimidobenzoyl-N-hydroxysuccinimide ester, 4-(4-N-Maleimidophenyl)-butyric acid hydrazide*HCl, 2-[N2-(4-Azido-2,3,5,6-tetrafluorobenzoyl)-N6-(6-biotinamidocaproyl)-L-ly- sinyl]ethylmethanethiosulfate, 2-{N2-[N6-(4-Azido-2,3,5,6-tetrafluorobenzoyl)-N6-(6-biotinamidocaproyl)-- L-lysinyl]}ethylmethanethiosulfate, N-Hydroxysuccinimide, N-hydroxysuccinimide ester ethane azide, N-hydroxysuccinimide ester tetraoxapentadecane azide, N-hydroxysuccinimide ester dodecaoxanonatriacontane azide, NHS-Phosphine, 3-(2-Pyridyldithio)propionylhydrazide, 2-pyridyldithiol-tetraoxatetradecane-N-hydroxysuccinimide, 2-pyridyldithiol-tetraoxaoctatriacontane-N-hydroxysuccinimide, N-(p-Maleimidophenyl)isocyanate, Succinimdyl 3-(bromoacetamido)propionate, NHS-Diazirine, NHS-SS-Diazirine, N-succinimidyl iodoacetate, N-Succinimidyl(4-iodoacetyl)aminobenzoate, Succinimidyl 4-(N-maleimido-methyl)cyclohexane-1-carboxylate, NHS-PEG2-Maliemide, NHS-PEG4-Maliemide, NHS-PEG6-Maleimide, NHS-PEG8-Maliemide, NHS-PEG12-Maliemide, NHS-PEG24-Maleimide, Succi nimidyl 4-(p-maleimido-phenyl)butyrate, Succinimidyl-6-(.beta.-maleimidopropionamido)hexanoate, 4-Succinimidyloxycarbonyl-methyl-.alpha.-(2-pyridyldithio)toluene, Succinimidyl-(4-psoralen-8-yloxy)butyrate, N-Succinimidyl 3-(2-pyridyldithio)propionate, Ethylene glycol bis (sulfo-succinimidyl succinate), N-(.epsilon.-Maleimidocaproyloxy)sulfosuccinimide ester, N-(.gamma.-Maleimidobutryloxy)sulfosuccinimide ester, N-(.kappa.-Maleimidoundecanoyloxy)sulfosuccinimide ester, Sulfo-NHS-LC-Diazirine, Sulfosuccinimidyl 6-(3'-[2-pyridyldithio]propionamido)hexanoate, m-Maleimidobenzoyl-N-hydroxysulfosuccinimide ester, N-Hydroxysuccinimide, Sulfo-NHS-Phosphine, Sulfosuccinimidyl 6-(4'-azido-2'-nitrophenylamino)hexanoate, Sulfo-NHS-(2-6-[Biotinamido]-2-(p-azidobezamido), Sulfo-NHS-Diazirine, Sulfo-NHS-SS-Diazirine, Sulfosucci nimidyl(4-iodo-acetyl)aminobenzoate, Sulfosuccinimidyl 4-(N-maleimidomethyl)cyclohexane-1-carboxylate, Sulfosuccinimidyl 4-(p-maleimidophenyl)butyrate, Tris-(2-Maleimidoethyl)amine (Trifunctional), and Tris-(succimimidyl aminotricetate) (Trifunctional).

[0538] The linkage between two out of the three components a), b), and c) of the complex according to the present invention may be directly or indirectly, i.e. two components directly adjoin or they may be linked by an additional component of the complex, e.g. a spacer or a linker.

[0539] A direct linkage may be realized preferably by an amide bridge, if the components to be linked have reactive amino or carboxy groups. More specifically, if the components to be linked are peptides, polypeptides or proteins, a peptide bond is preferred. Such a peptide bond may be formed using a chemical synthesis involving both components (an N-terminal end of one component and the C-terminal end of the other component) to be linked, or may be formed directly via a protein synthesis of the entire peptide sequence of both components, wherein both (protein or peptide) components are preferably synthesized in one step. Such protein synthesis methods include e.g., without being limited thereto, liquid phase peptide synthesis methods or solid peptide synthesis methods, e.g. solid peptide synthesis methods according to Merrifield, t-Boc solid-phase peptide synthesis, Fmoc solid-phase peptide synthesis, BOP (Benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate) based solid-phase peptide synthesis, etc. Alternatively, ester or ether linkages are preferred.

[0540] Moreover, in particular if the components to be linked are peptides, polypeptides or proteins, a linkage may occur via the side chains, e.g. by a disulfide bridge. Further components of other chemical nature, e.g. the at least one antigen or antigenic epitope if it is not of peptidic nature, may be likewise attached to the components of peptidic nature, e.g. the cell penetrating peptide, the at least one TLR peptide agonist, and the at least one antigen or antigenic epitope if it is of peptidic nature. The linkage via a side chain will preferably be based on side chain amino, thiol or hydroxyl groups, e.g. via an amide or ester or ether linkage. A linkage of a peptidic main chain with a peptidic side chain of another component may also be via an isopeptide bond. An isopeptide bond is an amide bond that is not present on the main chain of a protein. The bond forms between the carboxyl terminus of one peptide or protein and the amino group of a lysine residue on another (target) peptide or protein.

[0541] The complex according to the present invention may optionally comprise a spacer or linker, which are non-immunologic moieties, which are preferably cleavable, and which link component a) and b) and/or component a) and c), and/or component b) and c), and/or link consecutive antigens or antigenic epitopes, and/or link consecutive TLR peptide agonists, and/or link consecutive cell penetrating peptides, and/or which can be placed at the C-terminal part of components b) and/or c). A linker or spacer may preferably provide further functionalities in addition to linking of the components, and preferably being cleavable, more preferably naturally cleavable inside the target cell, e.g. by enzymatic cleavage. However, such further functionalities do in particular not include any immunological functionalities. Examples of further functionalities, in particular regarding linkers in fusion proteins, can be found in Chen X. et al., 2013: Fusion Protein Linkers: Property, Design and Functionality. Adv Drug Deliv Rev. 65(10): 1357-1369, wherein for example also in vivo cleavable linkers are disclosed. Moreover, Chen X. et al., 2013: Fusion Protein Linkers: Property, Design and Functionality. Adv Drug Deliv Rev. 65(10): 1357-1369 also discloses various linkers, e.g. flexible linkers and rigid linkers, and linker designing tools and databases, which can be useful in the complex according to the present invention or to design a linker to be used in the complex according to the present invention.

[0542] Said spacer may be peptidic or non-peptidic, preferably the spacer is peptidic. Preferably, a peptidic spacer consists of about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 amino acids, more preferably of about 1, 2, 3, 4, or 5 amino acids. The amino acid sequence of the peptidic spacer may be identical to that of the N-terminal or C-terminal flanking region of any of the components a), b), or c). Alternatively a peptidic spacer can consist of non-natural amino acid sequences such as an amino acid sequence resulting from conservative amino acid substitutions of said natural flanking regions or sequences of known cleavage sites for proteases such as an enterokinase target site (amino acid sequence: DDDK, SEQ ID NO: 16), factor Xa target site (amino acid sequence: IEDGR, SEQ ID NO: 17), thrombin target site (amino acid sequence: LVPRGS, SEQ ID NO: 18), protease TEV target site (amino acid sequence: ENLYFQG, SEQ ID NO: 19), PreScission protease target site (amino acid sequence LEVLFQGP, SEQ ID NO: 20), polycationic amino acids, e.g. poly K, furin target site (amino acid sequence RX(R/K)R, SEQ ID NO: 21). In a particular embodiment, the peptidic spacer does not contain any Cys (C) residues. In a preferred embodiment the linker sequence contains at least 20%, more preferably at least 40% and even more preferably at least 50% Gly or .beta.-alanine residues, e.g. GlyGlyGlyGlyGly (SEQ ID NO: 22), GlyGlyGlyGly (SEQ ID NO: 23), GlyGlyGly, CysGlyGly or GlyGlyCys, etc. Appropriate linker sequences can be easily selected and prepared by a person skilled in the art. They may be composed of D and/or L amino acids. Further examples of a peptidic spacer include the amino acid sequences EQLE (SEQ ID NO: 24) or TEWT (SEQ ID NO: 25) or any conservative substitutions thereof.

[0543] A non-peptidic spacer can include or may be an ester, a thioester, and a di-sulfide.

[0544] In particular, the complex according to the invention may comprise a spacer or linker, in particular a peptidic spacer, placed between component a) and b) and/or between component a) and c), and/or between component b) and c),. This peptidic spacer can be chosen by one skilled in the art so that it may be cut by the cell machinery once the complex comprising the cell penetrating peptide and the cargo molecule has been internalized.

[0545] When the complex comprises several antigens or antigenic epitopes or when the complex comprises several TLR peptide agonists, it will be clear for one skilled in the art that each of the antigens or antigenic epitopes and/or each of the TLR peptide agonists comprised in the complex of the invention can be either directly linked to each other or linked via spacers or linkers such as, e.g., a peptidic spacer consisting of a few amino acids. Alternatively, when the complex according to the present invention comprises several antigens or antigenic epitopes or when the complex comprises several TLR peptide agonists, it is also possible that some antigens or antigenic epitopes and/or some TLR peptide agonists comprised by the complex of the invention are directly linked to each other and some other antigens or antigenic epitopes and/or some other TLR peptide agonists are linked via spacers or linkers such as a peptidic spacer consisting of a few amino acids.

[0546] For example, two successive antigens or antigenic epitopes or two successive TLR peptide agonists comprised in the complex of the invention are linked to each other by spacers consisting of the natural flanking regions of said antigens or antigenic epitopes or of said TLR peptide agonists, respectively. For example, the spacer used to link a first antigen/antigenic epitope or a first TLR peptide agonist to a second antigen/antigenic epitope or to a second TLR peptide agonist, respectively, may consists of up to about 8 amino acids corresponding to up to about 4 amino acids of the N-terminal or C-terminal flanking region of the first antigen/antigenic epitope or the first TLR peptide agonist, followed by up to about 4 amino acids of the N-terminal or C-terminal flanking region of the second antigen/antigenic epitope or the second TLR peptide agonist. In an illustration of the present invention, the spacer used to link a first antigen/antigenic epitope or a first TLR peptide agonist ("antigen/epitope/TLR peptide agonist 1") to a second epitope ("antigen/epitope/TLR peptide agonist 2") consists of about 8 amino acids corresponding to any possible combination ranging from: 0 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 8 flanking amino acids of antigen/epitope/TLR peptide agonist 2, to 8 flanking amino acids of antigen/epitope/TLR peptide agonist 1 and 0 flanking amino acid of antigen/epitope/TLR peptide agonist 2, i.e. including 1 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 7 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 2 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 6 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 3 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 5 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 4 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 4 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 5 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 3 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 6 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 2 flanking amino acids of antigen/epitope/TLR peptide agonist 2, 7 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 1 flanking amino acid of antigen/epitope/TLR peptide agonist 2, 8 flanking amino acid of antigen/epitope/TLR peptide agonist 1 and 0 flanking amino acids of antigen/epitope/TLR peptide agonist 2. It will be understood that the total of 8 amino acids constituting a spacer linking two consecutive antigen/epitope/TLR peptide agonist is not an absolute value and the spacer could also be composed of a total of, for instance, 3 amino acids, 4 amino acids, 5 amino acids, 6 amino acids, 7 amino acids, 9 amino acids or 10 amino acids. Similarly, equivalent combinations as mentioned above are also an illustration of the invention in the situation where a spacer has less or more than 8 amino acids.

[0547] In another particular illustration of the present invention, the spacer used to link a first antigen/antigenic epitope or a first TLR peptide agonist ("antigen/epitope/TLR peptide agonist 1") to a second antigen/antigenic epitope or to a second TLR peptide agonist, respectively, ("antigen/epitopefTLR peptide agonist 2") consists of e.g. 1, 2, 3, 4, or 5 amino acids. More particularly, said spacer's amino acid sequence can correspond to the 4 amino acids of the N-terminal or C-terminal flanking region of antigen/epitope/TLR peptide agonist 1 or antigen/epitope/TLR peptide agonist 2. A spacer as described above may also be placed at the C-terminal part of the last antigen/epitope/TLR peptide agonist comprised in the complex according to the present invention.

[0548] The technics for linking two of the three components a), b), and c) are well documented in the literature and can depend on the nature of the at least one antigen or antigenic epitope. For instance, linkages between two of the three components a), b), and c) can be achieved via cleavable disulphide linkages through total stepwise solid-phase synthesis or solution-phase or solid-phase fragment coupling, stable amide, thiazolidine, oxime and hydrazine linkage, disulphide linkage, stable thiomaleimide linkage, peptide bond (including peptide bonds between amino acids of a fusion protein), or electrostatic or hydrophobic interactions.

[0549] Preferably, the at least one antigen or antigenic epitope comprised by the complex according to the present invention as well as any optional spacer or linker comprised by the complex according to the present invention are of peptidic nature. More preferably, all components of the complex according to the present invention, e.g. the cell penetrating peptide, the at least one antigen or antigenic epitope, which is a peptide, polypeptide or protein, the at least one TLR peptide agonist and any optional peptidic linker or spacer are linked in the complex according to the present invention by a peptide bond. Most preferably, the complex according to the present invention is thus a peptide, polypeptide or protein, such as a fusion protein, e.g. a recombinant fusion protein.

[0551] Arrangement of Components a), b), and c) in the Complex according to the Present Invention

[0552] The components a), b), and c) may be arranged in the complex according to the present invention in any way.

[0553] In particular if more than one cell penetrating peptide and/or more than one antigen or antigenic epitope and/or more than one TLR peptide agonist are comprised by the complex according to the present invention, the more than one cell penetrating peptide may be positioned in a non-consecutive manner, i.e. at least one antigen or antigenic epitope (component b)) and/or at least one TLR peptide agonist (component c)) may interrupt a stretch of consecutively positioned cell penetrating peptides and/or the cell penetrating peptides may be positioned with component b) and/or with component c) in an alternating manner. Similarly, the more than one antigen or antigenic epitope may be positioned in a non-consecutive manner, i.e. at least one cell penetrating peptide (component a)) and/or at least one TLR peptide agonist (component c)) may interrupt a stretch of consecutively positioned antigens or antigenic epitopes and/or the antigens or antigenic epitopes may be positioned with component a) and/or with component c) in an alternating manner. Similarly, the more than one TLR peptide agonist may be positioned in a non-consecutive manner, i.e. at least one cell penetrating peptide (component a)) and/or at least one antigen or antigenic epitope (component b)) may interrupt a stretch of consecutively positioned TLR peptide agonists and/or the TLR peptide agonists may be positioned with component a) and/or with component b) in an alternating manner.

[0554] However, it is preferred that the more than one cell penetrating peptide is positioned in the complex according to the present invention in a consecutive manner and/or the more than one antigen or antigenic epitope is positioned in the complex according to the present invention in a consecutive manner and/or the more than one TLR peptide agonist is positioned in the complex according to the present invention in a consecutive manner. This means in particular that all single units of a certain component, i.e. all cell penetrating peptides, all antigens or antigenic epitopes or all TLR peptide agonists, which are comprised by the complex are positioned in a stretch, which is not interrupted by any of the other two components. Rather, the other two components are positioned in the complex for example before or after such a stretch of all single units of said certain component. However, the single units of said certain component positioned consecutively in such a way may be linked to each other for example by a spacer or linker as described herein, which is not of the other two components.

[0555] It is particularly preferred that each of the components a), b), and c) is positioned in a consecutive manner.

[0556] Structurally each component a), b), and c) typically comprises a single main chain and at least one side chain. The term "main chain" (also "backbone chain"), as used in the context of the present invention, refers to the main continuous chain of covalently bond atoms in a molecule. For example, in peptides, polypeptides and proteins, the main chain (backbone) typically comprises alpha-carbon atoms and nitrogen atoms of the constituent amino acids linked by the peptide bond. The backbone does not include the side chains. The term "side chain" (also "pendant chain"), as used in the context of the present invention, refers to a chemical group that is attached to a core part of the molecule called "main chain" or backbone. For example, in peptides, polypeptides and proteins, the side chains typically represent the (main) parts of the constituent amino acids, which are attached to the alpha-carbon atoms of the backbone.

[0557] In the complex according to the present invention, the components a), b), and c) may be covalently linked via a linker or spacer as described herein or they may be directly covalently linked. Independently of whether a spacer or linker is used for covalent linkage or not, there are in principle four options of how two of the three components are linked to each other in the complex according to the present invention, namely: [0558] (i) via main-chain/main-chain linkage, [0559] (ii) via main-chain/side-chain linkage, [0560] (iii) via side-chain/main-chain linkage or [0561] (iv) via side-chain/side chain linkage.

[0562] Preferably, all three components a), b), and c) are linked via main-chain/main-chain linkage, thus resulting in particular in a main chain of the complex according to the present invention, which comprises the main chain of one or more cell penetrating peptide(s), the main chain of one or more antigen(s) or antigenic epitope(s), and the main chain of one or more TLR peptide agonist(s). In other words, the main chain of one or more cell penetrating peptide(s), the main chain of one or more antigen(s) or antigenic epitope(s), and the main chain of one or more TLR peptide agonist(s) constitute the main chain of the complex according to the present invention, optionally together with further components, for example linker(s), spacer(s), etc. Accordingly, the following arrangements of the components a), b), and c) are preferred, in particular if the at least one antigen or antigenic epitope is a peptide, polypeptide or protein, whereby said preferred arrangements are shown below in N-terminus.fwdarw.C-terminus direction of the main chain of the complex and wherein all three components a), b), and c) are linked via main-chain/main-chain linkage and may be optionally linked by a linker, a spacer or another additional component: [0563] (.alpha.) component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--component c) (at least one TLR peptide agonist); [0564] (.beta.) component c) (at least one TLR peptide agonist)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope); [0565] (.gamma.) component a) (cell penetrating peptide)--component c) (at least one TLR peptide agonist)--component b) (at least one antigen or antigenic epitope); [0566] (.delta.) component c) (at least one TLR peptide agonist)--component b) (at least one antigen or antigenic epitope)--component a) (cell penetrating peptide); [0567] (.epsilon.) component b) (at least one antigen or antigenic epitope)--component a) (cell penetrating peptide)--component c) (at least one TLR peptide agonist); or [0568] (.zeta.) component b) (at least one antigen or antigenic epitope)--component c) (at least one TLR peptide agonist)--component a) (cell penetrating peptide).

[0569] In particular if all three components a), b), and c) are linked via main-chain/main-chain linkage, it is preferred that the at least one antigen or antigenic epitope is positioned C-terminally of the cell penetrating peptide, whereby the cell penetrating peptide and the at least one antigen or antigenic epitope are optionally linked by a further component, e.g. a linker, a spacer, or by the at least one TLR peptide agonist. Accordingly, this corresponds to the arrangements (.alpha.), (.beta.), and (.gamma.) from the arrangements shown above, i.e. from the above arrangements arrangements (.alpha.), (.beta.), and (.gamma.) are more preferred.

[0570] Even more preferably, the at least one antigen or antigenic epitope is positioned C-terminally of the cell penetrating peptide, whereby the cell penetrating peptide and the at least one antigen or antigenic epitope are optionally linked by a further component, e.g. a linker, a spacer, but not by the at least one TLR peptide agonist. Accordingly, this corresponds to the arrangements (.alpha.) and (.beta.) from the arrangements shown above, i.e. from the above arrangements arrangements (.alpha.) and (.beta.) are even more preferred. Particularly preferably, the complex according to the present invention is a recombinant polypeptide or a recombinant protein and the components a) to c) are positioned in N-terminus.fwdarw.C-terminus direction of the main chain of said complex in the order: [0571] (.alpha.) component a)--component b)--component c); or [0572] (.beta.) component c)--component a)--component b),

[0573] wherein the components may be linked by a further component, in particular by a linker or a spacer.

[0574] Particularly preferred is arrangement (.alpha.), wherein the at least one TLR agonist comprises or consists of at least one TLR2 agonist, for example: [0575] (.alpha.1) component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s); [0576] (.alpha.2) component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s), one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s); [0577] (.alpha.3) component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s) and one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s); or [0578] (.alpha.4) component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s).

[0579] Alternatively, in such an arrangement comprising a TLR2 peptide agonist, additional TLR peptide agonists may also be arranged at other positions in the complex, for example: [0580] (.alpha.5) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s); [0581] (.alpha.6) one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s); or [0582] (.alpha.7) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s).

[0583] Particularly preferred is arrangement (.beta.), wherein the at least one TLR agonist comprises or consists of at least one TLR4 agonist, for example: [0584] (.beta.1) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope); [0585] (.beta.2) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s), one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope); [0586] (.beta.3) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s) and one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope); or [0587] (.beta.4) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope).

[0588] Alternatively, in such an arrangement comprising a TLR4 peptide agonist, additional TLR peptide agonists may also be arranged at other positions in the complex, for example: [0589] (.beta.5) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s); [0590] (.beta.6) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s); or [0591] (.beta.7) one or more TLR4 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR4 peptide agonist(s)--component a) (cell penetrating peptide)--component b) (at least one antigen or antigenic epitope)--one or more TLR2 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR2 peptide agonist(s) and one or more TLR5 peptide agonist, e.g. 1, 2, 3, 4, or 5 TLR5 peptide agonist(s).

[0592] Alternatively, only two of the three components a), b), and c) are linked via main-chain/main-chain linkage in the complex according to the present invention.

[0593] For example components a) and b) are linked via main-chain/main-chain linkage, resulting thus in the following arrangements of the components a) and b) in the complex, shown in N-terminus.fwdarw.C-terminus direction of the main chain of the complex, whereby the components a) and b) may be optionally linked by a further component, e.g. a linker, a spacer etc.: [0594] (1) cell penetrating peptide (a)--antigen/antigenic epitope (b); or [0595] (2) antigen/antigenic epitope (b)--cell penetrating peptide (a).

[0641] The term "vector", as used in the context of the present invention, refers to a nucleic acid molecule, preferably to an artificial nucleic acid molecule, i.e. a nucleic acid molecule which does not occur in nature. A vector in the context of the present invention is suitable for incorporating or harboring a desired nucleic acid sequence. Such vectors may be storage vectors, expression vectors, cloning vectors, transfer vectors etc. A storage vector is a vector which allows the convenient storage of a nucleic acid molecule. Thus, the vector may comprise a sequence corresponding, e.g., to a desired antibody or antibody fragment thereof according to the present invention. An expression vector may be used for production of expression products such as RNA, e.g. mRNA, or peptides, polypeptides or proteins. For example, an expression vector may comprise sequences needed for transcription of a sequence stretch of the vector, such as a promoter sequence. A cloning vector is typically a vector that contains a cloning site, which may be used to incorporate nucleic acid sequences into the vector. A cloning vector may be, e.g., a plasmid vector or a bacteriophage vector. A transfer vector may be a vector which is suitable for transferring nucleic acid molecules into cells or organisms, for example, viral vectors. A vector in the context of the present invention may be, e.g., an RNA vector or a DNA vector. Preferably, a vector is a DNA molecule. For example, a vector in the sense of the present application comprises a cloning site, a selection marker, such as an antibiotic resistance factor, and a sequence suitable for multiplication of the vector, such as an origin of replication. Preferably, a vector in the context of the present application is a plasmid vector. Preferably, a vector in the context of the present application is an expression vector.

[0698] Thus, the present invention also provides a vaccine comprising at least one component selected from: [0699] (i) a complex according to the present invention as described above, [0700] (ii) a nucleic acid according to the present invention as described above, [0701] (iii) a vector according to the present invention as described above, [0702] (iv) a host cell according to the present invention as described above, and [0703] (v) a cell loaded with a complex according to the present invention as described above.

[0704] Preferably, the vaccine according to the present invention comprises the complex according to the present invention as described above.

[0705] Thereby, the above details described for the composition according to the present invention regarding more than one of the components (i) to (v), also apply for the vaccine according to the present invention.

[0706] As used in the context of the present invention, the term "vaccine" refers to a biological preparation that provides innate and/or adaptive immunity, typically to a particular disease, preferably cancer. Thus, a vaccine supports in particular an innate and/or an adaptive immune response of the immune system of a subject to be treated. For example, the antigen or antigenic epitope of the complex according to the present invention typically leads to or supports an adaptive immune response in the patient to be treated, and the TLR peptide agonist of the complex according to the present invention may lead to or support an innate immune response.

[0707] The inventive composition, in particular the inventive vaccine, may also comprise a pharmaceutically acceptable carrier, adjuvant, and/or vehicle as defined below for the inventive pharmaceutical composition. In the specific context of the inventive composition, in particular of the inventive vaccine, the choice of a pharmaceutically acceptable carrier is determined in principle by the manner in which the inventive composition, in particular the inventive vaccine, is administered. The inventive composition, in particular the inventive vaccine, can be administered, for example, systemically or locally. Routes for systemic administration in general include, for example, transdermal, oral, parenteral routes, including subcutaneous, intravenous, intramuscular, intraarterial, intradermal and intraperitoneal injections and/or intranasal administration routes. Routes for local administration in general include, for example, topical administration routes but also intradermal, transdermal, subcutaneous, or intramuscular injections or intralesional, intracranial, intrapulmonal, intracardial, intranodal and sublingual injections. More preferably, inventive composition, in particular the vaccines, may be administered by an intradermal, subcutaneous, intranodal or intramuscular route. Even more preferably, the inventive composition, in particular the vaccine, may be administered by subcutaneous, intranodal or intramuscular route. Particularly preferably, the inventive composition, in particular the vaccines, may be administered by subcutaneous or intranodal route. Most preferably, the inventive composition, in particular the vaccines may be administered by subcutaneous route. Inventive composition, in particular the inventive vaccines, are therefore preferably formulated in liquid (or sometimes in solid) form.

[0708] The suitable amount of the inventive composition, in particular the inventive vaccine, to be administered can be determined by routine experiments with animal models. Such models include, without implying any limitation, rabbit, sheep, mouse, rat, dog and non-human primate models. Preferred unit dose forms for injection include sterile solutions of water, physiological saline or mixtures thereof. The pH of such solutions should be adjusted to about 7.4. Suitable carriers for injection include hydrogels, devices for controlled or delayed release, polylactic acid and collagen matrices. Suitable pharmaceutically acceptable carriers for topical application include those which are suitable for use in lotions, creams, gels and the like. If the inventive composition, in particular the inventive vaccine, is to be administered orally, tablets, capsules and the like are the preferred unit dose form. The pharmaceutically acceptable carriers for the preparation of unit dose forms which can be used for oral administration are well known in the prior art. The choice thereof will depend on secondary considerations such as taste, costs and storability, which are not critical for the purposes of the present invention, and can be made without difficulty by a person skilled in the art.

[0709] The inventive composition, in particular the inventive vaccine, can additionally contain one or more auxiliary substances in order to further increase its immunogenicity. A synergistic action of the inventive complex as defined above and of an auxiliary substance, which may be optionally contained in the inventive vaccine as described above, is preferably achieved thereby. Depending on the various types of auxiliary substances, various mechanisms can come into consideration in this respect. For example, compounds that permit the maturation of dendritic cells (DCs), for example lipopolysaccharides, TNF-alpha or CD40 ligand, form a first class of suitable auxiliary substances. In general, it is possible to use as auxiliary substance any agent that influences the immune system in the manner of a "danger signal" (LPS, GP96, etc.) or cytokines, such as GM-CSF, which allow an immune response produced by the immune-stimulating adjuvant according to the invention to be enhanced and/or influenced in a targeted manner. Particularly preferred auxiliary substances are cytokines, such as monokines, lymphokines, interleukins or chemokines, that further promote the innate immune response, such as IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12, IL-13, IL-14, IL-15, IL-16, IL-17, IL-18, IL-19, IL-20, IL-21, IL-22, IL-23, IL-24, IL-25, IL-26, IL-27, IL-28, IL-29, IL-30, IL-31, IL-32, IL-33, IFN-alpha, IFN-beta, IFN-gamma, GM-CSF, G-CSF, M-CSF, LT-beta or TNF-alpha, growth factors, such as hGH.

[0710] Further additives which may be included in the inventive vaccine are emulsifiers, such as, for example, Tween.RTM.; wetting agents, such as, for example, sodium lauryl sulfate; colouring agents; taste-imparting agents, pharmaceutical carriers; tablet-forming agents; stabilizers; antioxidants; preservatives.

[0711] The inventive composition, in particular the inventive vaccine, can also additionally contain any further compound, which is known to be immune-stimulating due to its binding affinity (as ligands) to human Toll-like receptors TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, or due to its binding affinity (as ligands) to murine Toll-like receptors TLR1, TLR2, TLR3, TLR4, TLR5, TLR6, TLR7, TLR8, TLR9, TLR10, TLR11, TLR12 or TLR13.

[0712] Another class of compounds, which may be added to an inventive composition, in particular to an inventive vaccine, in this context, may be CpG nucleic acids, in particular CpG-RNA or CpG-DNA. A CpG-RNA or CpG-DNA can be a single-stranded CpG-DNA (ss CpG-DNA), a double-stranded CpG-DNA (dsDNA), a single-stranded CpG-RNA (ss CpG-RNA) or a double-stranded CpG-RNA (ds CpG-RNA). The CpG nucleic acid is preferably in the form of CpG-RNA, more preferably in the form of single-stranded CpG-RNA (ss CpG-RNA). The CpG nucleic acid preferably contains at least one or more (mitogenic) cytosine/guanine dinucleotide sequence(s) (CpG motif(s)). According to a first preferred alternative, at least one CpG motif contained in these sequences, in particular the C (cytosine) and the G (guanine) of the CpG motif, is unmethylated. All further cytosines or guanines optionally contained in these sequences can be either methylated or unmethylated. According to a further preferred alternative, however, the C (cytosine) and the G (guanine) of the CpG motif can also be present in methylated form.

[0713] Moreover, the present invention also provides the complex as described above or cells loaded with said complex or a composition or a vaccine as described above for use in the prevention and/or treatment of diseases or disorders including for example cancers, hematological disorders, infectious diseases, autoimmunity disorders and transplant rejections, whereby cancer is preferred.

[0714] In addition, the present invention also provides the complex as described above or cells loaded with said complex or a composition as described above for use as an imaging or diagnostic composition.

[0715] The present invention also provides a pharmaceutical composition, in particular a vaccine composition as described above, and a method for treating a subject, preferably a mammalian subject, and most preferably a human subject, who is suffering from a disease or disorder, in particular from a disorder that can be treated by immunotherapy such as cancers, infectious diseases, autoimmunity disorders and transplant rejections.

[0716] In particular, the present invention provides a pharmaceutical composition comprising at least one complex according to the present invention or at least one cell loaded with a complex according to the present invention, and optionally a pharmaceutically acceptable carrier and/or vehicle, or any excipient, buffer, stabilizer or other materials well known to those skilled in the art, in particular the pharmaceutical composition comprising at least one complex according to the present invention or at least one cell loaded with a complex according to the present invention and a pharmaceutically acceptable carrier.

[0717] As a further ingredient, the inventive pharmaceutical composition may in particular comprise a pharmaceutically acceptable carrier and/or vehicle. In the context of the present invention, a pharmaceutically acceptable carrier typically includes the liquid or non-liquid basis of the inventive pharmaceutical composition. If the inventive pharmaceutical composition is provided in liquid form, the carrier will typically be pyrogen-free water; isotonic saline or buffered (aqueous) solutions, e.g phosphate, citrate etc. buffered solutions. Particularly for injection of the inventive inventive pharmaceutical composition, water or preferably a buffer, more preferably an aqueous buffer, may be used, containing a sodium salt, preferably at least 30 mM of a sodium salt, a calcium salt, preferably at least 0.05 mM of a calcium salt, and optionally a potassium salt, preferably at least 1 mM of a potassium salt. According to a preferred embodiment, the sodium, calcium and, optionally, potassium salts may occur in the form of their halogenides, e.g. chlorides, iodides, or bromides, in the form of their hydroxides, carbonates, hydrogen carbonates, or sulfates, etc. Without being limited thereto, examples of sodium salts include e.g. NaCl, NaI, NaBr, Na.sub.2CO.sub.3, NaHCO.sub.3, Na.sub.2SO.sub.4, examples of the optional potassium salts include e.g. KCl, KI, KBr, K.sub.2CO.sub.3, KHCO.sub.3, K.sub.2SO.sub.4, and examples of calcium salts include e.g. CaCl.sub.2, CaI.sub.2, CaBr.sub.2, CaCO.sub.3, CaSO.sub.4, Ca(OH).sub.2. Furthermore, organic anions of the aforementioned cations may be contained in the buffer. According to a more preferred embodiment, the buffer suitable for injection purposes as defined above, may contain salts selected from sodium chloride (NaCl), calcium chloride (CaCl.sub.2) and optionally potassium chloride (KCl), wherein further anions may be present additional to the chlorides. CaCl.sub.2 can also be replaced by another salt like KCl. Typically, the salts in the injection buffer are present in a concentration of at least 30 mM sodium chloride (NaCl), at least 1 mM potassium chloride (KCl) and at least 0.05 mM calcium chloride (CaCl.sub.2). The injection buffer may be hypertonic, isotonic or hypotonic with reference to the specific reference medium, i.e. the buffer may have a higher, identical or lower salt content with reference to the specific reference medium, wherein preferably such concentrations of the afore mentioned salts may be used, which do not lead to damage of cells due to osmosis or other concentration effects. Reference media are e.g. liquids occurring in "in vivd" methods, such as blood, lymph, cytosolic liquids, or other body liquids, or e.g. liquids, which may be used as reference media in "in vitro" methods, such as common buffers or liquids. Such common buffers or liquids are known to a skilled person. Saline (0.9% NaCl) and Ringer-Lactate solution are particularly preferred as a liquid basis.

[0718] However, one or more compatible solid or liquid fillers or diluents or encapsulating compounds may be used as well for the inventive pharmaceutical composition, which are suitable for administration to a subject to be treated. The term "compatible" as used herein means that these constituents of the inventive pharmaceutical composition are capable of being mixed with the complex according to the present invention as defined above in such a manner that no interaction occurs which would substantially reduce the pharmaceutical effectiveness of the inventive pharmaceutical composition under typical use conditions. Pharmaceutically acceptable carriers, fillers and diluents must, of course, have sufficiently high purity and sufficiently low toxicity to make them suitable for administration to a subject to be treated. Some examples of compounds which can be used as pharmaceutically acceptable carriers, fillers or constituents thereof are sugars, such as, for example, lactose, glucose and sucrose; starches, such as, for example, corn starch or potato starch; cellulose and its derivatives, such as, for example, sodium carboxymethylcellulose, ethylcellulose, cellulose acetate; powdered tragacanth; malt; gelatin; tallow; solid glidants, such as, for example, stearic acid, magnesium stearate; calcium sulfate; vegetable oils, such as, for example, groundnut oil, cottonseed oil, sesame oil, olive oil, corn oil and oil from theobroma; polyols, such as, for example, polypropylene glycol, glycerol, sorbitol, mannitol and polyethylene glycol; alginic acid.

[0719] The inventive pharmaceutical composition may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term parenteral as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional, intracranial, transdermal, intradermal, intrapulmonal, intraperitoneal, intracardial, intraarterial, intranodal and sublingual injection or infusion techniques. Preferably, the inventive pharmaceutical composition may be administered intradermally, intramuscularly, intranodally or subcutaneously. More preferably the inventive pharmaceutical composition may be administered intramuscularly, intranodally or subcutaneously. Even more preferably the inventive pharmaceutical composition may be administered intranodally or subcutaneously. Most preferably, the inventive pharmaceutical composition may be administered subcutaneously.

[0720] Preferably, the inventive pharmaceutical composition may be administered by parenteral injection, more preferably by subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional, intracranial, transdermal, intradermal, intrapulmonal, intraperitoneal, intracardial, intraarterial, intranodal and sublingual injection or via infusion techniques. Sterile injectable forms of the inventive pharmaceutical compositions may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example as a solution in 1.3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation of the inventive pharmaceutical composition.

[0721] For intravenous, cutaneous or subcutaneous injection, or injection at the site of affliction, the active ingredient will preferably be in the form of a parenterally acceptable aqueous solution which is pyrogen-free and has suitable pH, isotonicity and stability. Those of relevant skill in the art are well able to prepare suitable solutions using, for example, isotonic vehicles such as Sodium Chloride Injection, Ringer's Injection, Lactated Ringer's Injection. Preservatives, stabilizers, buffers, antioxidants and/or other additives may be included, as required. Whether it is a polypeptide, peptide, or nucleic acid molecule, other pharmaceutically useful compound according to the present invention that is to be given to an individual, administration is preferably in a "prophylactically effective amount" or a "therapeutically effective amount" (as the case may be), this being sufficient to show benefit to the individual. The actual amount administered, and rate and time-course of administration, will depend on the nature and severity of what is being treated.

[0722] The inventive pharmaceutical composition as defined above may also be administered orally in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient, i.e. the inventive transporter cargo conjugate molecule as defined above, is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.

[0723] The inventive pharmaceutical composition may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, e.g. including diseases of the skin or of any other accessible epithelial tissue. Suitable topical formulations are readily prepared for each of these areas or organs. For topical applications, the inventive pharmaceutical composition may be formulated in a suitable ointment, containing the inventive immunostimulatory composition, particularly its components as defined above, suspended or dissolved in one or more carriers. Carriers for topical administration include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water. Alternatively, the inventive pharmaceutical composition can be formulated in a suitable lotion or cream. In the context of the present invention, suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.

[0724] In this context, prescription of treatment, e.g. decisions on dosage etc. when using the above pharmaceutical composition is typically within the responsibility of general practitioners and other medical doctors, and typically takes account of the disorder to be treated, the condition of the individual patient, the site of delivery, the method of administration and other factors known to practitioners. Examples of the techniques and protocols mentioned above can be found in REMINGTON'S PHARMACEUTICAL SCIENCES, 16th edition, Osol, A. (ed), 1980.

[0725] Accordingly, the inventive pharmaceutical composition typically comprises a "safe and effective amount" of the components of the inventive pharmaceutical composition, in particular of the complex according to the present invention as defined above and/or cells loaded with said complex. As used herein, a "safe and effective amount" means an amount of the complex according to the present invention that is sufficient to significantly induce a positive modification of a disease or disorder, i.e. an amount of the complex according to the present invention or cells loaded with said complex, that elicits the biological or medicinal response in a tissue, system, animal or human that is being sought. An effective amount may be a "therapeutically effective amount" for the alleviation of the symptoms of the disease or condition being treated and/or a "prophylactically effective amount" for prophylaxis of the symptoms of the disease or condition being prevented. The term also includes the amount of active complex sufficient to reduce the progression of the disease, notably to reduce or inhibit the tumor growth or infection and thereby elicit the response being sought, in particular such response could be an immune response directed against the antigens or antigenic epitopes comprised in by the complex (i.e. an "inhibition effective amount"). At the same time, however, a "safe and effective amount" is small enough to avoid serious side-effects, that is to say to permit a sensible relationship between advantage and risk. The determination of these limits typically lies within the scope of sensible medical judgment. A "safe and effective amount" of the components of the inventive pharmaceutical composition, particularly of the complex according to the present invention as defined above, will furthermore vary in connection with the particular condition to be treated and also with the age and physical condition of the patient to be treated, the body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, the activity of the specific components a), b), and c) of the complex according to the present invention as defined above, the severity of the condition, the duration of the treatment, the nature of the accompanying therapy, of the particular pharmaceutically acceptable carrier used, and similar factors, within the knowledge and experience of the accompanying doctor. The inventive pharmaceutical composition may be used for human and also for veterinary medical purposes, preferably for human medical purposes, as a pharmaceutical composition in general or as a vaccine.

[0726] Pharmaceutical compositions, in particular vaccine compositions, or formulations according to the invention may be administered as a pharmaceutical formulation which can contain a complex according to the present invention in any form described herein.

[0727] The terms "pharmaceutical formulation" and "pharmaceutical composition" as used in the context of the present invention refer in particular to preparations which are in such a form as to permit biological activity of the active ingredient(s) to be unequivocally effective and which contain no additional component which would be toxic to subjects to which the said formulation would be administered.

[0728] In the context of the present invention, an "efficacy" of a treatment can be measured based on changes in the course of a disease in response to a use or a method according to the present invention. For example, the efficacy of a treatment of cancer can be measured by a reduction of tumor volume, and/or an increase of progression free survival time, and/or a decreased risk of relapse post-resection for primary cancer. More specifically for cancer treated by immunotherapy, assessment of efficacy can be by the spectrum of clinical patterns of antitumor response for immunotherapeutic agents through novel immune-related response criteria (irRC), which are adapted from Response Evaluation Criteria in Solid Tumors (RECIST) and World Health Organization (WHO) criteria (J. Natl. Cancer Inst. 2010, 102(18): 1388-1397). The efficacy of prevention of infectious disease is ultimately assessed by epidemiological studies in human populations, which often correlates with titres of neutralizing antibodies in sera, and induction of multifunctional pathogen specific T cell responses. Preclinical assessment can include resistance to infection after challenge with infectious pathogen. Treatment of an infectious disease can be measured by inhibition of the pathogen's growth or elimination of the pathogen (and, thus, absence of detection of the pathogen), correlating with pathogen specific antibodies and/or T cell immune responses.

[0729] Pharmaceutical compositions, in particular vaccine compositions, or formulations according to the invention may also be administered as a pharmaceutical formulation which can contain antigen presenting cells loaded with a complex according to the invention in any form described herein.

[0730] The vaccine and/or the composition according to the present invention may also be formulated as pharmaceutical compositions and unit dosages thereof, in particular together with a conventionally employed adjuvant, immunomodulatory material, carrier, diluent or excipient as described above and below, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, or capsules filled with the same, all for oral use, or in the form of sterile injectable solutions for parenteral (including subcutaneous and intradermal) use by injection or continuous infusion.

[0731] In the context of the present invention, in particular in the context of a pharmaceutical composition and vaccines according to the present invention, injectable compositions are typically based upon injectable sterile saline or phosphate-buffered saline or other injectable carriers known in the art. Such pharmaceutical compositions and unit dosage forms thereof may comprise ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

[0732] Examples of suitable adjuvants and/or immunomodulatory materials in the context of the present invention include MPL.RTM. (Corixa), aluminum-based minerals including aluminum compounds (generically called Alum), ASO1-4, MF59, CalciumPhosphate, Liposomes, Iscom, polyinosinic:polycytidylic acid (polylC), including its stabilized form poly-ICLC (Hiltonol), CpG oligodeoxynucleotides, Granulocyte-macrophage colony-stimulating factor (GM-CSF), lipopolysaccharide (LPS), Montanide, polylactide co-glycolide (PLG), Flagellin, Soap Bark tree saponins (QS21), amino alkyl glucosamide compounds (e.g. RC529), two component antibacterial peptides with synthetic oligodeoxynucleotides (e.g. IC31), Imiquimod, Resiquimod, Immunostimulatory sequences (ISS), monophosphoryl lipid A (MPLA), Fibroblast-stimulating lipopeptide (FSL1), and anti-CD40 antibodies.

[0733] Compositions, in particular pharmaceutical compositions and vaccines, according to the present invention may be liquid formulations including, but not limited to, aqueous or oily suspensions, solutions, emulsions, syrups, and elixirs. The compositions may also be formulated as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may contain additives including, but not limited to, suspending agents, emulsifying agents, non-aqueous vehicles and preservatives. Suspending agents include, but are not limited to, sorbitol syrup, methyl cellulose, glucose/sugar syrup, gelatin, hydroxyethyl cellulose, carboxymethyl cellulose, aluminum stearate gel, and hydrogenated edible fats. Emulsifying agents include, but are not limited to, lecithin, sorbitan monooleate, and acacia. Preservatives include, but are not limited to, methyl or propyl p-hydroxybenzoate and sorbic acid. Dispersing or wetting agents include but are not limited to poly(ethylene glycol), glycerol, bovine serum albumin, Tween.RTM., Span.RTM..

[0734] Compositions, in particular pharmaceutical compositions and vaccines, according to the present invention may also be formulated as a depot preparation, which may be administered by implantation or by intramuscular injection.

[0735] Compositions, in particular pharmaceutical compositions and vaccines, according to the present invention may also be solid compositions, which may be in the form of tablets or lozenges formulated in a conventional manner. For example, tablets and capsules for oral administration may contain conventional excipients including, but not limited to, binding agents, fillers, lubricants, disintegrants and wetting agents. Binding agents include, but are not limited to, syrup, accacia, gelatin, sorbitol, tragacanth, mucilage of starch and polyvinylpyrrolidone. Fillers include, but are not limited to, lactose, sugar, microcrystalline cellulose, maizestarch, calcium phosphate, and sorbitol. Lubricants include, but are not limited to, magnesium stearate, stearic acid, talc, polyethylene glycol, and silica. Disintegrants include, but are not limited to, potato starch and sodium starch glycollate.

[0736] Wetting agents include, but are not limited to, sodium lauryl sulfate. Tablets may be coated according to methods well known in the art.

[0737] Compositions, in particular pharmaceutical compositions and vaccines, according to the present invention may also be administered in sustained release forms or from sustained release drug delivery systems.

[0738] Moreover, the compositions, in particular pharmaceutical compositions and vaccines, according to the present invention may be adapted for delivery by repeated administration.

[0739] Further materials as well as formulation processing techniques and the like, which are useful in the context of compositions, in particular pharmaceutical compositions and vaccines, according to the present invention or in the context of their preparation are set out in "Part 5 of Remington's "The Science and Practice of Pharmacy", 22.sup.nd Edition, 2012, University of the Sciences in Philadelphia, Lippincott Williams & Wilkins".

[0740] According to still another aspect, the present invention provides a method of preparing a pharmaceutical composition according to the present invention comprising the step of mixing complex according to the present invention or cells, in particular antigen-presenting cells, loaded with a complex according to the present invention, and a pharmaceutically acceptable carrier.

[0741] Accordingly, the complex according to the present invention and the cell loaded with a complex according to the present invention may be used (for the preparation of a pharmaceutical composition and/or the preparation of a vaccine) for the prevention, treatment and/or amelioration of any of the diseases and disorders as defined herein, in particular those that can be treated or prevented by immunotherapy such as cancers and infectious diseases.

[0742] In another aspect, the invention provides imaging or diagnosis compositions ("diagnostic compositions"). A still other aspect concerns methods for delivering an imaging agent and methods for diagnosing a disease or disorder in a subject, preferably a mammalian subject, and most preferably a human subject who is suspected of suffering from a medical disorder, and in particular a cancer, infectious disease, autoimmunity disorder and transplant rejection.

[0743] The formulations and modes of administration described herewith for the pharmaceutical compositions can also be suitable to the imaging or diagnosis compositions ("diagnostic compositions") according to the invention.

[0744] In a further aspect, the present invention also relates to a kit-of-parts comprising at least one of: [0745] (i) a complex according to the present invention as described above, [0746] (ii) a nucleic acid according to the present invention as described above, [0747] (iii) a vector according to the present invention as described above, [0748] (iv) a host cell according to the present invention as described above, and [0749] (v) a cell loaded with a complex according to the present invention as described above.

[0750] In particular, the kit-of-parts of the invention may comprise more than one component (i) to (v).

[0751] For example, the different complexes (i) comprised by the kit-of-parts as described above may differ in either component a), i.e. in the cell penetrating peptides, in component b), i.e. in the antigens or antigenic epitopes or in the subsets of more than one antigen or antigenic epitope, or in component c), i.e. in the TLR peptide agonist or in the subset of more than one TLR peptide agonist; or the different complexes (i) comprised by the kit-of-parts as described above may differ in two out of the three components a), b), and c); or the different complexes (i) comprised by the kit-of-parts as described above may differ in all three components a), b), and c) of the complex. Accordingly, the different nucleic acids (ii) comprised by the kit-of-parts as described above may differ in that they encode such different complexes; the different vectors (iii) comprised by the kit-of-parts as described above may differ in that they comprise such different nucleic acids; the different host cells (iv) comprised by the kit-of-parts as described above may differ in that they comprise such different vectors; and the different cells loaded with a complex (v) comprised by the kit-of-parts as described above may differ in that they are loaded with such different complexes.

The kit may also comprise additional reagents including, for instance, preservatives, growth media, and/or buffers for storage and/or reconstitution of the above-referenced components, washing solutions, and the like. In addition, the kit-of-parts according to the present invention may optionally contain instructions of use.

[0753] Moreover, the present invention also provides a vaccination kit for treating, preventing and/or stabilizing a cancer or an infectious disease, comprising the pharmaceutical composition according to the present invention or a vaccine according to the present invention and instructions for use of said pharmaceutical composition or of said vaccine.

[0754] Thus, the present invention also provides a kit comprising the complex according to the present invention as described herein, the cell according to the present invention as described herein, the composition according to the present invention as described herein, the vaccine according to the present invention as described herein, and/or the pharmaceutical composition according to the present invention as described herein.

Example 1

In Vitro Human Dendritic Cell Maturation

[0893] The goal of this study was to investigate the capacity of a complex according to the present invention to induce maturation of dendritic cells. In the present study, the complex according to the present invention is a fusion protein, comprising the cell-penetrating peptide "Z13", a protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR4 peptide agonist "EDA". Accordingly, a fused protein with the EDA peptide at the N-terminal position and different control conjugated proteins without Z13 or EDA or both were designed.

[0894] Namely, the following constructs were designed, whereby in the amino acid sequence the cell-penetrating peptide "Z13" is shown underlined and the TLR peptide agonist "EDA" is shown in italics:

[0913] The EDAZ13Mad5, Z13Mad5 and Mad5 proteins were investigated for their capacity to induce human dendritic cell (DC) maturation. After incubation during 48 h with 300 nM of protein, activation markers expression (CD86, CD40, CD83 and HLA-DR) was assessed on the human DCs by FACS (FIGS. 1-4). Specific buffers of each protein were used as negative controls.

[0914] Results are shown for CD40 in FIG. 1, for CD86 in FIG. 2, for HLADR in FIG. 3, and for CD83 in FIG. 4. Whereas EDAZ13Mad5 induced maturation of human DCs, shown by the up-regulation of CD86, HLADR and CD83, Z13Mad5 and Mad5 proteins were not able to activate human DCs. These results indicate that the EDA portion of the protein is responsible for the up-regulation of the activation markers on the human DCs.

Example 2

In Vitro Epitope Presentation (MHC I)

[0915] The goal of this study was to assess functional MHC class I-restricted cross-presentation in a murine in an vitro system using bone marrow derived dendritic cells (BMDCs) and splenocytes from different TCR transgenic mice. To this end, the constructs EDAZ13Mad5 and Mad5 (described above in Example 1) and the construct EDAMad5 were used:

[0922] BMDCs were loaded overnight with 300 nM of with the EDAMad5, EDAZ13Mad5 and Mad5 proteins containing OVACD8, OVACD4 and gp100 epitopes. Processing and presentation of these MHC I-restricted OVACD8 and gp100 epitopes were monitored by measuring the in vitro proliferation of naive OVA.sub.257-264-specific CD8.sup.+ T cells from OT-1 T cell receptor (TCR) transgenic mice and gp100-specific CD8.sup.+ T cells from P-mel T cell TCR transgenic mice respectively. Accordingly, efficient MHC class I-restricted presentation of OVACD8 epitope and gp100 epitope was monitored after 4 days with CFSE-labeled OT1 cells and P-Mel cells respectively. Processing and presentation of MHC Il-restricted OVACD4 epitope was monitored by measuring the in vitro proliferation of naive OVA.sub.323-339-specific CD4.sup.+ T cells from OT-2 T cell receptor (TCR) transgenic mice. Accordingly, efficient MHC class II-restricted presentation of OVACD4 epitope was monitored after 4 days with CFSE-labeled OT2 cells. As control, BMDCs were pulsed for 1 h with 5 uM peptide (one experiment representative of 2 individual experiments).

[0923] Results are shown in FIG. 5. Similar cross-presentation and processing capacity of all assessed Mad5-based proteins were observed.

Example 3

CD8 T Cell Immune Response

[0924] To investigate the efficacy of EDA-conjugated proteins in inducing polyclonal CD8.sup.+ T cell response, C57BL/6 mice were vaccinated twice (Wk0 and Wk2), by subcutaneous injection of either 2 nmol or 10 nmol of the constructs EDAZ13Mad5 or EDAMad5 (described in Examples 1 and 2). Positive control group was vaccinated with Mad5 and the TLR4 agonist MPLA (equimolar to EDA). Two doses were assessed 2 nmol of the construct (FIG. 6) and 10 nmol of the construct (FIG. 7). 3-4 mice were used per group.

[0925] Seven days after the last vaccination, mice were bled and pentamer staining was performed to monitor the OVA-specific immune response in the blood. In FIG. 8, the percentage of pentamer positive CD8+ T cells is shown for all groups and both doses tested.

[0926] These data show that interestingly the immune response is lower at 10 nmol compared to 2 nmol. At both doses, 2 nmol and 10 nmol, the vaccine mediated immune response was observed more consistently in the EDAZ13Mad5 group in contrast to the EDAMad5 group. Moreover, there is an increased immune response when the TLR4 agonist is conjugated with the vaccine.

Example 4

Vaccine Efficacy on Tumor Growth in a Benchmark EG.7-OVA Tumor Model

[0927] To evaluate the effect of EDA construct proteins on tumor growth control, the s.c. model of EG.7-OVA thymoma cells was chosen. C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank. After tumor implantation, mice were vaccinated at day 5 and 13 with 10 nmol of one of the following constructs (cf. Examples 1 and 2 for construct description): EDAZ13Mad5, EDAMad5, Mad5, or Mad5 and MPLA (equimolar to EDA) s.c. in the right flank. Tumor size was measured with a caliper.

[0928] FIG. 9 shows the tumor growth of 7 mice per group (mean.+-.SEM); *, p<0.05 EDAZ13Mad5 versus control group (2-way Anova test). FIG. 10 shows individual tumor growth curves (7 individual mice per group). FIG. 11A shows the survival curve of 7 mice per group; *, p<0.05 EDAZ13Mad5 versus control group (Log-rank test). FIG. 11B shows the tumor-free progression curve of 7 mice per group; *, p<0.05 EDAZ13Mad5 versus control group (Log-rank test).

[0929] The results show that in a therapeutic setting, EDAZ13Mad5 was the only protein vaccine to significantly control the tumor growth compared to the control group with a significant better tumor free progression curve and survival curve.

[0930] The results therefore suggest that the construct protein EDAZ13Mad5 is a highly potent vaccine for controlling the tumor growth in a therapeutic setting.

Example 5

Vaccine Efficacy on Tumor Growth in a Melanoma Metastasis Model

[0931] To assess the efficacy in a lung metastasis model using B16-OVA tumor cells in a semi-therapeutic setting, different construct proteins were used: EDAMad5, EDAZ13Mad5, Z13Mad5+MPLA (cf. Examples 1 and 2 for design of the constructs), and MPLA alone. C57BL/6 mice were implanted i.v. with 1.times.10.sup.5 B16-OVA melanoma tumor cells and at the same time (d0) 2 nmol of the vaccine (EDAMad5, EDAZ13Mad5, Z13Mad5+MPLA, MPLA alone) was administered by subcutaneous injection in the right flank. Nine days later, mice were vaccinated a second time with the same dose. Further control groups were vaccinated with 2 nmol of Z13Mad5 and the TLR4 agonist MPLA (equimolar to EDA) or MPLA alone. Mice were euthanized at day 13 and lung recovered. Number of metastasis foci was counted for each lung. The results are shown in FIG. 12.

[0932] The results show that the conjugate EDAZ13Mad5 is as potent as Z13Mad5+MPLA to inhibit tumor metastasis in the lung. Furthermore, EDA-Mad5 is less potent than EDAZ13Mad5, indicating a crucial role of Z13 in vaccine efficacy.

Example 6

Vaccine Efficacy on Tumor Growth in a Melanoma Metastasis Model--Prophylactic Setting

[0933] Furthermore, the efficacy of the different construct proteins EDAMad5, EDAZ13Mad5, and Z13Mad5+MPLA (cf. Examples 1 and 2 for design of the constructs) was assessed in a lung metastasis model in a prophylactic setting. C57BL/6 mice were vaccinated 21 and 7 days before implantation of tumor cells (d-21 and d-7) by subcutaneous injection of 2 nmol of EDAZ13Mad5, EDAMad5 or Z13Mad5+MPLA (equimolar to EDA) s.c. in the right flank. At day 0, mice were implanted i.v. with 1.times.10.sup.5 B16-OVA melanoma tumor cells. Mice were euthanized at day 14 and lung recovered. Results are shown in FIG. 13.

Example 7

Design of further Constructs comprising a TLR2 Peptide Agonist

[0934] Herein, the complex according to the present invention is again a fusion protein, comprising the cell-penetrating peptide "Z13", the protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR2 peptide agonist "Anaxa". Accordingly, fused proteins with the Anaxa peptide at the C-terminal or N-terminal position were designed.

[0935] Namely, the following constructs were designed, whereby in the amino acid sequence the cell-penetrating peptide "Z13" is shown underlined and the TLR peptide agonist "Anaxa" is shown in italics:

Example 8

TLR2 Binding (HEK-hTLR2 Cell Lines)

[0948] The goal of this study was to assess whether the Z13Mad5Anaxa and AnaxaZ13Mad5 construct proteins (cf. Example 7 for design of these construct proteins) were able to bind TLR2 as an agonist. HEK-Blue.TM. hTLR2 were seeded in flat 96-well plate in culture medium, stimulated with 0.3 .mu.M, 1 .mu.M or 3 .mu.M of AnaxaZ13Mad5 or Z13Mad5Anaxa and incubated at 37.degree. C. for 24 h. Positive control was performed with 500 ng/ml of Pam3CSK4, a TLR2 agonist.

[0949] To monitor the activation of NF-.kappa.B/AP1, twenty microliters of the supernatant were added to QuantiBlue.RTM. detection medium and incubated at 37.degree. C. for 1 h before OD reading (620 nm). Results are shown in FIG. 14A.

[0950] The secretion of IL-8 in the supernatant was quantified by ELISA. Results are shown in FIG. 14B.

[0951] Results (FIG. 14A, B) showed that Z13Mad5Anaxa and AnaxaZ13Mad5 are similarly able to bind to TLR2 in a dose dependent manner.

Example 9

In Vivo Induction of Specific CD8.sup.+ T Cells

[0952] To investigate the efficacy of the Anaxa-conjugated proteins of Example 7 in the induction of CD8.sup.+ T cell responses, C57BL/6 mice were vaccinated twice (Wk0 and Wk2), by subcutaneous injection of 2 nmol of AnaxaZ13Mad5 or 2 nmol of Z13Mad5Anaxa. Seven days after the last vaccination, mice were bled and to monitor the OVA-specific immune response in the blood, pentamer staining was performed (one experiment with 4 mice per group). Results are shown in FIGS. 15 and 16.

[0953] These data indicate that both, the Z13Mad5Anaxa vaccine and the AnaxaZ13Mad5 construct, elicit a strong immune response.

Example 10

Therapeutic Effect on Tumor Growth

[0954] To evaluate the effect of the Anaxa-conjugated construct proteins designed in Example 7 on tumor growth control, a benchmark tumor model was used, namely the s.c. implantation of EG.7-OVA thymoma cells.

[0955] C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank. After tumor implantation, the three groups of 7 mice each were vaccinated s.c. in the right flank at day 5 and 13 by subcutaneous injection of 10 nmol of either AnaxZ13Mad5 (group 1), Z13Mad5Anaxa (group 2) or Z13Mad5 and Pam3CSK4 (equimolar to Anaxa; group 3). In order to compare the effect to a protein mixed with an external adjuvant, a control group was vaccinated with Z13Mad5 and Pam3CSK4 (equimolar to Anaxa). Tumor size was measured with a caliper. Results are shown in FIG. 17-19.

[0956] In a therapeutic schedule, Z13Mad5Anaxa and AnaxaZ13Mad5 are better protein vaccines for controlling tumor growth compared to the control group, i.e. co-injection of Z13Mad5 and Pam3CSK showing a significant better survival curve. In particular, Z13Mad5Anaxa and AnaxaZ13Mad5 demonstrate significantly higher efficacy than Z13Mad5 administrated separately with Pam3CSK4. The results therefore suggest that the construct proteins Z13Mad5Anaxa and AnaxaZ13Mad5 are promising conjugate-vaccines for controlling the tumor growth in a therapeutic setting.

Example 11

Therapeutic Effect on Tumor Growth--Comparison of Constructs with Different TLR Agonists

[0957] The goal of this study was to compare the efficacy of the different construct protein vaccines conjugated to different TLR agonist, namely EDAZ13Mad5 and Z13Mad5Anaxa of Example 1 and 7, on tumor growth control. To this end, C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG.7-OVA thymoma cells in the left flank as described previously in Example 10. Mice (7 individual mice per group) were vaccinated s.c. in the right flank at day 5 and 13 with 2 nmol of either EDAZ13Mad5, Z13Mad5Anaxa or co-injection of Z13Mad5+MPLA (equimolar to EDA).

[0958] Results are shown in FIGS. 20, 21 and 22. In this experimental setting, Z13Mad5Anaxa, EDAZ13Mad5, and Z13Mad5+MPLA were similarly able to significantly control tumor growth. Moreover, these data indicate that Z13Mad5Anaxa is the best construct to significantly control tumor growth and EDAZ13Mad5 was slightly better than Z13Mad5+MPLA in this experimental setting.

[0959] To identify the optimal dose of the conjugate vaccine, three different doses (0.5 nmol, 2 nmol and 10 nmol) of Z13Mad5Anaxa (cf. Example 7) were assessed for their ability to control tumor growth. The dose effect of Z13Mad5Anaxa construct was evaluated in the s.c. model of EG.7-OVA thymoma cells as described previously in Example 10. After tumor implantation, mice were vaccinated twice (at day 5 and at day 13 after tumor implantation) in a therapeutic setting at 0.5, 2 or 10 nmol of Z13Mad5Anaxa.

[0960] C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank and vaccinated twice (d5 and d13) by subcutaneous injection of either 0.5 nmol, 2 nmol or 10 nmol of Z13Mad5Anaxa in the right flank. Tumor size was measured with a caliper.

[0961] The tumor growth of 7 mice per group is depicted in FIG. 23. Those data show that the doses of 0.5 and 2 nmol are at least as efficacious as 10 nmol for controlling tumor growth.

Example 13

Effect of Different Routes of Administration of Z13Mad5Anaxa

[0962] This study was based on the previous Examples demonstrating the efficacy of Z13Mad5Anaxa conjugate vaccine (cf. Example 7), which is able to elicit specific immune responses and is efficacious for controlling tumor growth in the subcutaneous tumor model EG7 as shown above.

[0963] To investigate the effect of subcutaneous, intramuscular and intradermal routes of administration, immune responses elicited by subcutaneous, intramuscular and intradermal injection were compared. Intradermal injections were performed using the PLEASE.RTM. device from Pantec Biosolutions.

[0964] Mice were vaccinated three times every two weeks (Wk0, Wk2 and Wk4) with 0.5 or 2 nmol of Z13Mad5Anaxa (cf. Example 7). In order to target several lymph nodes, the 1st and the 3rd vaccinations were performed in the right flank whereas the 2nd was done in the left flank. SIINFEKL-specific CD8+ T cell response was analyzed 1 week after the 2nd and the 3rd vaccination in the blood. FIG. 24 shows the SIINFEKL-specific CD8 T cell responses after each vaccination detected in the blood of C57BL/6 mice vaccinated three times (Wk0, Wk2 and Wk4) s.c., i.d. or i.m. with 0.5 nmol (FIG. 24A) or 2 nmol (FIG. 24B) of Z13Mad5Anaxa. Blood was obtained from mice 7 days after the 2nd and the 3rd vaccination and multimer staining was performed (one experiment with 4 mice per group).

[0965] The results indicate that at the two doses assessed (0.5 and 2 nmol), (i) all routes of administration tested elicited a SIINFEKL-specific CD8 immune response and (ii) the subcutaneous vaccination elicited the strongest SIINFEKL-specific CD8 immune response. For subcutaneous administration, the maximum response was reached after the 3nd vaccination and still maintained after the 3rd vaccination. The SIINFEKL-specific CD8 immune response after the 2nd vaccination elicited by intradermal and intramuscular vaccinations is lower compared to subcutaneous vaccination and is not enhanced after the 3rd vaccination.

[0966] Next, the effector function and the exhaustion status of SIINFEKL-specific CD8 T cells was evaluated by analyzing KLRG 1 (Killer cell lectin-like receptor subfamily G member 1) and PD-1 respectively.

[0967] To this end, C57BL/6 mice were vaccinated three times (Wk0, Wk2 and Wk4) s.c., i.d. or i.m. with 2 nmol of Z13Mad5Anaxa (cf. Example 7). Blood was obtained from mice 7 days after the 2nd and the 3rd vaccination and FACS staining was performed. KLRG1 and PD-1 expression were analyzed on multimer-positive CD8 T cells (one experiment with 4 mice per group). Results are shown in FIG. 25.

[0968] These data indicate that the expression of KLRG 1 is strongly increasing on SIINFEKL-specific CD8 T cells after subcutaneous vaccination. After i.d. or i.m. vaccination, the observed effects were lower. The percentage of KLRG 1-positive cells among SIINFEKL-specific CD8 T cells is also enhanced after s.c. vaccination (data not shown).

[0969] In contrast to KLRG 1, PD-1 expression is decreasing with the time and the vaccinations, for subcutaneous and intramuscular vaccination routes. This suggests that SIINFEKL-specific CD8 T cells are not exhausted. The percentage of PD1-positive cells among SIINFEKL-specific CD8 T cells is also reduced after s.c. and i.m. vaccination (data not shown). It is important to note that PD-1 expression is higher after the 2nd vaccination when mice were vaccinated subcutaneously, reflecting the early activation status of specific T cells (Keir, M. E., et al., PD-1 and its ligands in tolerance and immunity. Annu Rev Immunol, 2008. 26: p. 677-704).

[0970] The expression of the late exhaustion marker Tim-3 was also analyzed. A very low expression as observed for all groups.

[0971] Taken together, results indicate that subcutaneous vaccination elicits the best specific CD8 immune response compared to intramuscular or intradermal injections.

Example 14

Intranodal Route of Administration

[0972] Based on the previous experiments (Example 13), the intranodal route of administration was additionally investigated. To this end, the immune response elicited by intranodal injection of Z13Mad5Anaxa (cf. Example 7) was investigated.

[0973] For this purpose, mice were first injected with Evans Blue subcutaneously in order to allow easily visualizing the lymph nodes for injection and inject intranodally without invasive surgery, for example as described in Jewell, C. M., S. C. Lopez, and D. J. Irvine, In situ engineering of the lymph node microenvironment via intranodal injection of adjuvant-re/easing polymer particles. Proc Natl Acad Sci USA, 2011. 108(38): p. 15745-50.

[0974] C57BL/6 mice were vaccinated two times every two weeks (Wk0 and Wk2) intranodally with 0.5 nmol of Z13Mad5Anaxa (cf. Example 7). The 1st vaccination was performed in the right inguinal lymph node, whereas the second vaccination was done in the left inguinal lymph node. Blood was obtained from mice 7 days after the 2nd vaccination and multimer staining was performed (3 mice per group). In other words, SIINFEKL-specific CD8+ T cell response was analyzed one week after the 2nd vaccination in the blood. FIG. 26 shows the SIINFEKL-specific CD8 T cell responses. Those data indicate that also intranodal injection was able to elicit SIINFEKL-specific CD8 T cells.

Example 15

Vaccination Schedule

[0975] The vaccination schedule evaluation work was initiated with the objective to identify the impact of the third vaccination using the same Z13Mad5Anaxa construct as described above (cf. Example 7). The subcutaneous route was chosen given the previous results.

[0976] In the experiment first two vaccinations were performed at wk0 and wk2 with a 3rd vaccination either at wk4 (FIG. 27A) or at wk8 (FIG. 27B). Thus, C57BL/6 mice were vaccinated three times (FIG. 27A and C: Wk0, Wk2 and Wk4 and FIG. 27B and D: Wk0, Wk2 and Wk8) s.c. with 2 nmol of Z13Mad5Anaxa. Blood was obtained from mice 7 days after last vaccination and pentamer staining was performed (one experiment with 4 mice per group). Accordingly, SIINFEKL-specific CD8+ T cell response was analyzed 1 week after the 2nd and the 3rd vaccination (FIGS. 27A and B). Additionally, the effector function of SIINFEKL-specific T cells was evaluated by analyzing the expression of KLRG 1 on specific CD8 T cells (FIGS. 27C and D).

[0977] The data indicate that compared to control the percentage of SIINFEKL-specific CD8 T cells was significantly increased at all time points tested (Vac2 and Vac3) as well as in both vaccination schedules (FIGS. 27A and B).

[0978] Interestingly, the third vaccination at Wk4 allowed to most prominently increasing the percentage of SIINFEKL-specific CD8 T cells (FIG. 27A). The same cells also demonstrate an improved effector function through higher KLRG 1 expression (FIG. 27C). In contrast, with a third vaccination performed at Wk8 no improvement from the second to the third vaccination could be observed in the SIINFEKL-specific immune response and in the KLRG 1 expression.

[0979] Taken together, these results indicate that the CD8 immune response could be increased by shorten the delay between the second and the third vaccination.

[0980] Given that an earlier third vaccination seems to increase immune response, in the next study two short schedules of vaccination were investigated:

[0981] i) three vaccinations at day 0, day 3 and day 7 and

[0982] ii) three vaccinations at day 0, day 7 and day 14.

[0983] Again, C57BL/6 mice were used and vaccination was performed s.c. with 0.5 nmol of Z13Mad5Anaxa (cf. Example 7). Multimer staining was performed on blood samples obtained one week after the 2nd and the 3rd vaccination (one experiment with 4 mice per group).

[0984] Thus, SIINFEKL-specific CD8+ T cell response was analyzed one week after the 2nd and the 3rd vaccination (FIGS. 28A and D). Additionally, the effector function of SIINFEKL-specific T cells was evaluated by analyzing the expression of KLRG 1 on specific CD8 T cells (FIGS. 28B and 28E) and the exhaustion status by analyzing the PD-1 expression of specific T cells (FIGS. 28C and 28F).

[0985] The data indicate that--similarly to the first study regarding the vaccination schedule described above--compared to control the percentage of SIINFEKL-specific CD8 T cells was increased at all time points tested (Vac2 and Vac3) as well as in both vaccination schedules (FIGS. 28A and B).

[0986] However, compared to the schedule wk0-wk2-wk4, a schedule with vaccinations at Day0, Day3 and Day7 did not elicit such a high SIINFEKL-specific CD8 T cell immune response. Concerning the schedule with vaccinations at Day0, Day7 and Dayl4, the SIINFEKL-specific CD8 T cell immune response elicited is better compared to the previous schedule (d0-d3-d7) but is not maintained after the 3rd vaccination.

[0987] Taken together, vaccination schedule data set indicates that the Wk0-Wk2-Wk4 vaccination schedule is the best vaccination schedule for inducing potent OVA-specific CD8 immune response with high effector function.

Example 16

Capacity of TLR Agonist-CPP Conjugate Constructs to Activate Murine Antigen-Presenting Cells (APCs)

[0988] To investigate the effect of both, the CPP component and the TLR agonist component in a complex according to the present invention, again the fusion proteins as described above (cf. Examples 1, 2 and 7) were used.

[0989] In addition, a further "control peptide" was designed, which is also a fusion protein and which comprises the protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR2 peptide agonist "Anaxa" (i.e. without cell penetrating peptide). Accordingly, the following control construct was additionally designed:

TABLE-US-00035 Mad5Anaxa Sequence: [SEQ ID NO: 32] MHHHHHHESL KISQAVHAAH AEINEAGREV VGVGALKVPR NQDWLGVPRF AKFASFEAQG ALANIAVDKA NLDVEQLESI INFEKLTEWT GSSTVHEILC KLSLEGDHST PPSAYGSVKP YTNFDAE

[0990] Molecular weight: 13933 Da

[0991] Characteristics: [0992] Mad5 cargo contains OVACD4, gp100CD8, EalphaCD4 and OVACD8 epitopes [0993] Contains the 35-mer peptide of Annexin in C-terminal position [0994] Storage buffer: 50 mM Tris-HCl, 150 mM NaCl, 10% Glycerol, 2 mM DTT, 0.5 M L-Arginine, pH 8 [0995] Endotoxin level: Batch 1--12.15 EU/mg

[0996] The aim of this study was to evaluate the capacity of two exemplary complexes according to the present invention, namely EDAZ13Mad5 (cf. Example 1) and Z13Mad5Anaxa (cf. Example 7), to promote antigen-presenting cells activation in comparison to reference complexes lacking either the cell penetrating peptide component Z13 (Mad5Anaxa, cf. above; EDAMad5, cf. Example 2) or the TLR agonist (Z13Mad5, cf. Example 1).

[0997] To this end, the capacity of the above mentioned constructs to promote antigen-presenting cells (APC) activation was assessed in bone marrow-derived dendritic cells (BMDCs), which express all TLRs except TLR7.

[0998] BMDCs were seeded in flat 96-well plate in culture medium, stimulated with 1 .mu.M of either Z13Mad5Anaxa (cf. Example 7), Mad5Anaxa (cf. above), Z13Mad5 (cf. Example 1), EDAZ13Mad5 (cf. Example 1) or EDAMad5 (cf. Example 2) and incubated for 24 h at 37.degree. C.

[0999] The APC activation was investigated by monitoring the secretion of IL-6 in the culture supernatant of BMDCs. IL-6 secretion was quantified by ELISA in the supernatant.

[1000] The results are shown in FIG. 29. These data clearly show that Z13Mad5Anaxa was able to activate BMDCs, whereas no such activation was observed when the cells were cultured in presence of Z13Mad5 or Mad5Anaxa. This suggests that not only the TLR agonist (Anaxa or EDA) is critical for the activation of macrophages and dendritic cells, but that the CPP is also needed. Also the presence of the CPP without the TLR agonist is not sufficient, but indeed both, CPP and TLR agonist are critical for the activation of macrophages and dendritic cells.

[1001] Those results were confirmed by using another cell line, namely in the Raw 264.7 mouse macrophage cell line, which expresses all TLRs except TLR5 (Applequist, S. E., R. P. Wallin, and H. G. Ljunggren, Variable expression of Toll-like receptor in murine innate and adaptive immune cell lines. Int Immunol, 2002. 14(9): p. 1065-74).

[1002] Raw 264.7 cells were seeded in flat 96-well plate in culture medium, stimulated with 1 .mu.M of either Z13Mad5Anaxa (cf. Example 7), Mad5Anaxa (cf. above) or Z13Mad5 (cf. Example 1) and incubated for 24 h at 37.degree. C.

[1003] In Raw 264.7 cells the APC activation was investigated by monitoring the secretion of TNF-.alpha. in the culture supernatant of Raw 264.7. TNF-a secretion was quantified by ELISA in the supernatant. The results are shown in FIG. 30.

[1004] It is thought that the CPP may facilitate the entry of the molecule into the cells, allowing a better targeting of intracellular TLR.

[1005] Taken together, the data reveal the critical role of both, CPP and TLR agonist, within the conjugate constructs to activate APC. This effect may be due to helping the entry of the construct into the cells, therefore resulting in an optimal targeting of the intracellular TLR.

Example 17

Ability of the Conjugate Constructs to Bind to Human TLR4

[1006] It was recently shown that the Anaxa peptide owns an adjuvant activity by signaling through TLR2 (WO 2012/048190 A1), whereas the EDA peptide is a natural ligand for TLR4 (Okamura, Y., et al., The extra domain A of fibronectin activates Toll-like receptor 4. J Biol Chem, 2001. 276(13): p. 10229-33).

[1007] Moreover, as shown above in Example 8 and FIG. 14, a complex according to the present invention comprising the Anaxa peptide as TLR agonist, for example Z13Mad5Anaxa, is able to bind to human TLR2 and to promote the secretion of IL-8 by HEK-hTLR2 cells (cf. Example 8, FIG. 14).

[1008] In the present study, the ability of complexes according to the present invention comprising either the Anaxa peptide as TLR agonist or the EDA peptide as TLR agonist to bind to human TLR4 was evaluated. To this end, HEK cells transfected with human TLR4 (HEK-hTLR4) were seeded in flat 96-well plate in culture medium, stimulated with 1 .mu.M of either Z13Mad5Anaxa (cf. Example 7), Mad5Anaxa (cf. above), Z13Mad5 (cf. Example 1), EDAZ13Mad5 (cf. Example 1) or EDAMad5 (cf. Example 2) and incubated for 24 h at 37.degree. C. IL-8 secretion was quantified by ELISA in the supernatant.

[1009] Results are shown in FIG. 31. As expected, incubation of HEK-hTLR4 with EDAZ13Mad5 resulted in remarkable IL-8 secretion, indicating binding of EDAZ13Mad5 to TLR4. In line with the results obtained in Example 16, the IL-8 secretion of EDAMad5 (without the CPP) was remarkably lower as compared to EDAZ13Mad5, showing the effect of the presence of a CPP. The Z13Mad5 construct, which does not comprise a TLR agonist, showed no IL-8 secretion, indicating--as expected--a lack of binding to TLR4.

[1010] Interestingly, incubation of HEK-hTLR4 with the construct Z13Mad5Anaxa resulted in the most pronounced IL-8 secretion, indicating binding of Z13Mad5Anaxa to TLR4. This is astonishing, since Anaxa was previously hypothesized to be a TLR2 agonist. Again, the same construct but without the CPP (Mad5Anaxa) resulted in remarkably lower IL-8 secretion, confirming the results obtained in Example 16.

[1011] Taken together, these data (i) confirm the results obtained in Example 16, (ii) confirm that EDA is indeed a TLR4 agonist, and (iii) show surprisingly that the Anaxa peptide is also a TLR4 agonist (in addition to being a TLR2 agonist, cf. Example 8 and FIG. 14).

Example 18

Vaccine Efficacy on Tumor Growth in a Lung Metastasis Model--Semi-Therapeutic Setting: TLR Agonist EDA

[1012] This study is based on Example 6, showing the efficacy of a complex according to the present invention, namely EDAZ13Mad5, in a melanoma lung metastasis model in a prophylactic setting (cf. FIG. 13).

[1013] In the present study the same lung metastasis model was used as well as the construct proteins EDAZ13Mad5 and Z13Mad5+MPLA (cf. Examples 1 and 2 for design of the constructs). However, in the semi-therapeutic setting, C57BL/6 mice were vaccinated at the same time as tumor cells were implanted (d0) and, for a second time, at nine days after implantation (d9). Vaccination was performed by subcutaneous injection of 2 nmol of EDAZ13Mad5, Z13Mad5+MPLA (equimolar to EDA) or MPLA s.c. in the right flank. At day 0, mice were implanted i.v. with 1.times.10.sup.5 B16-OVA melanoma tumor cells and vaccinated twice (d0 and d9) by subcutaneous injection of 2 nmol of EDAZ13Mad5, Z13Mad5+MPLA (equimolar to EDA) or MPLA alone s.c. in the right flank. Mice were euthanized at day 13 and lung recovered.

[1014] Results are shown in FIG. 32.

[1015] The results show that EDAZ13Mad5 is slightly more potent than Z13Mad5+MPLA to inhibit the growth of melanoma metastasis. In addition, no adjuvant effect was observed in mice injected with MPLA only.

[1016] Both, EDAZ13Mad5 and Z13Mad5+MPLA, significantly inhibit the growth of melanoma metastasis in the lung in prophylactic and semitherapeutic settings.

Example 19

Vaccine Efficacy on Tumor Growth in a Lung Metastasis Model--Semi-Therapeutic Setting: TLR Agonist Anaxa

[1017] This study is based on Example 18 with the same model (semitherapeutic settings) and experimental schedule. However, the effect of complexes according to the present invention comprising the "Anaxa" peptide as TLR agonist were investigated--instead of the EDA TLR agonist as in Example 18.

[1018] To this end, C57BL/6 mice were implanted i.v. with 1.times.10.sup.5 B16-OVA melanoma tumor cells and vaccinated twice (d0 and d9) by subcutaneous injection of 0.5 nmol of Z13Mad5Anaxa, Mad5Anaxa or Z13Mad5+Pam3CSK4 (equimolar to Anaxa) s.c. in the right flank. Mice were euthanized at day 21 and the lung was recovered. Number of metastasis foci was counted for each lung. The results are shown in FIG. 33.

[1019] The results show that Z13Mad5Anaxa is sensibly more potent than Z13Mad5+Pam3CSK4 to inhibit the growth of melanoma metastasis. In contrast, Mad5Anaxa was not able to control metastasis growth in the lung, underlining again the importance of CPP.

[1020] Altogether, the B16-OVA lung metastasis experiment showed that Z13Mad5Anaxa was highly efficacious in inhibiting the growth of melanoma metastasis in the lung.

Example 20

Vaccine Efficacy in a Glioblastoma Model

[1021] In this study, another cancer model was used, namely a glioblastoma model. Glioma is the most frequent form of primary brain tumors in adults, with glioblastoma multiforme (GBM) being the most lethal. This tumor is notorious for its highly invasive and aggressive behavior. Currently, the best treatment against GBM is a regimen involving a combination of surgery, chemotherapy and radiotherapy, which has a median survival period of only 14.6 months. There is an urgent, unmet medical need for new treatment modalities that improve the prognosis of glioma patients. T-cell mediated immunotherapy is a conceptually attractive treatment option to use in conjunction with existing modalities for glioma, in particular highly invasive GBM.

[1022] The Gl261 glioma is a carcinogen-induced mouse glioma model. This model represents one of the very few brain tumor models developed in immunocompetent animals, that has growth characteristics similar to human GBM (Newcomb, E. and D. Zagzag, The murine GL261 glioma experimental model to assess novel brain tumor treatments, in CNS Cancer Models, Markers, Prognostic, Factors, Targets, and Therapeutic Approaches, E. G. Van Meir, Editor. 2009, Humana Press: Atlanta. p. 227-241; Jacobs, V. L., et al., Current review of in vivo GBM rodent models: emphasis on the CNS-1 tumour model. ASN Neuro, 2011. 3(3): p. e00063). Low numbers of intracranially transplanted Gl261 cells formed intracranial tumors in C57BL/6 mice (Zhu, X., et al., Poly-/CLC promotes the infiltration of effector T cells into intracranial gliomas via induction of CXCL 10 in IFN-alpha and IFN-gamma dependent manners. Cancer Immunol lmmunother, 2010. 59(9): p. 1401-9; Zhu, X., et al., Toll like receptor-3 ligand poly-/CLC promotes the efficacy of peripheral vaccinations with tumor antigen-derived peptide epitopes in murine CNS tumor models. J Transl Med, 2007. 5: p. 10). The cells are moderately immunogenic: they are able to elicit tumor-specific immune response at the tumor site. However, the tumor-specific immune cells are not capable of complete tumor clearance.

[1023] Recently, M. Ollin generated a new Gl261 model (Ohlfest, J. R., et al., Vaccine injection site matters: qualitative and quantitative defects in CDB T cells primed as a function of proximity to the tumor in a murine glioma model. J Immunol, 2013. 190(2): p. 613-20) by transfecting Gl261 cell line with the "Quad Cassette" expressing four peptides presented by H-2b class I or II molecules: human gp100.sub.25-33, chicken OVA.sub.257-264, chicken OVA.sub.323-339, and mouse I-E.alpha..sub.52-68. The Quad-Gl261 cell line also stably expresses luciferase, which allows the follow-up of tumor growth by bioluminescence.

[1024] The goal of this study was to assess the efficacy of a complex according to the present invention in the Quad-Gl261 glioblastoma model.

[1025] The effect of a complex according to the present invention, namely Z13Mad5Anaxa (cf. Example 7) was evaluated in the above described glioblastoma model. T cell homing at the tumor site was therefore analyzed in Gl261-Quad tumor-bearing mice vaccinated twice (Wk1 and Wk3) with Z13Mad5Anaxa vaccine. A group vaccinated with Z13Mad5 and Anaxa (equimolar to Z13Mad5Anaxa) administrated separately was used as control. Briefly, C57BL/6 mice were implanted i.c. (intracranially) with 5.times.10.sup.5 Gl261-Quad tumor cells and vaccinated twice (at d7 and d21 following implantation) by s.c. injection of 2 nmol of Z13Mad5Anaxa (group 1) or 2 nmol of Z13Mad5 and 2 nmol of Anaxa (group 2). At Wk4, the blood and the brain infiltrating leukocytes (BILs) were analyzed, whereby SIINFEKL-specific CD8 T cells were quantified in blood and in BILs at d28 by multimer staining (5-8 mice per group). Results are shown in FIG. 34.

[1026] In general, low frequency of SIINFEKL-specific CD8 T cells was quantified in the blood. However, a higher percentage of SIINFEKL-specific CD8 T cells was observed in the blood of Z13Mad5Anaxa-vaccinated mice. In all groups, there was a sensibly stronger accumulation of SIINFEKL-specific CD8 T cells in the BILs.

[1027] After two vaccinations with Z13Mad5Anaxa, the frequency of SIINFEKL-specific cells CD8+ T cells in the BILs was 2-fold higher (24%) than with Z13Mad5+Anaxa (12%).

[1028] Next, cytokine secretion was assessed. To this end, C57BL/6 mice were implanted i.c. with 5.times.10.sup.5 Gl261-Quad tumor cells and vaccinated twice (d7 and 21) by s.c. injection of 2 nmol of Z13Mad5Anaxa or 2 nmol of Z13Mad5 and 2 nmol of Anaxa. BILs were isolated and cultured during 6 h with matured BMDCs loaded or not with SIINFEKL peptide in presence of BrefeldinA before intracellular staining for cytokines. Results are shown in FIG. 35.

[1029] Despite heterogeneity, a high level of cytokine secretion was observed for brain-infiltrating CD8 T cells from mice vaccinated with Z13Mad5Anaxa. These results demonstrate that Z13Mad5Anaxa vaccine was able to elicit a stronger SIINFEKL specific CD8 T cell immune response in the brain of tumor-bearing mice with potent effector function.

[1030] The results obtained are indicating that Z13Mad5Anaxa is efficacious for eliciting high brain infiltrating SIINFEKL-specific CD8 immune response. Z13Mad5Anaxa is able to promote the secretion of cytokine by antigen-specific CD8 T cells in the brain.

Example 21

Vaccine Efficacy on Survival in the Gl261-Quad Glioblastoma Model

[1031] In an independent experiment, the survival of control and Z13Mad5Anaxa-vaccinated mice was monitored. The therapeutic settings were three consecutive vaccinations with 2 nmol of Z13Mad5Anaxa at day 7, 21 and 35, post i.c. tumor implantation.

[1032] C57BL/6 mice were implanted i.c. with 5.times.10.sup.5 Gl261-Quad tumor cells and vaccinated three times (d7, d21 and d35) by s.c. injection of 2 nmol of Z13Mad5Anaxa. Mice were weight daily and euthanized when weight loss reached more than 15%. Results are shown in FIG. 36.

[1033] The results show that Z13Mad5Anaxa therapeutic vaccination is more efficacious than the control group with a median survival prolonged by 10 days.

Example 22

Vaccine Efficacy in a Subcutaneous Tumor Model--Prophylactic Setting

[1034] This study is based on the results obtained in Example 10 as shown in FIGS. 17-19.

[1035] To evaluate the effect of the Anaxa-conjugated construct proteins designed in Example 7 on tumor growth control, a benchmark tumor model was used, namely the s.c. implantation of EG.7-OVA thymoma cells. In contrast to Example 10, wherein vaccination was performed on days 5 and 13, in the present study a prophylactic setting was evaluated, wherein mice were vaccinated 21 and 7 days before tumor implantation.

[1036] C57BL/6 mice were vaccinated twice (d-21 and d-7) by s.c. injection of 0.5 nmol of Z13Mad5Anaxa in the right flank and then implanted at day0 s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank and. Tumor size was measured with a caliper.

[1037] The results are shown in FIG. 37 with tumor volume (FIG. 37A) and survival rate (FIG. 37B). The data is showing that prophylactic vaccination with Z13Mad5Anaxa is highly efficacious for controlling tumor growth and survival rate. The volume of the tumor is highly significantly decreased in mice treated with Z13Mad5Anaxa as compared to control mice. The survival rate is highly significantly increased in mice treated with Z13Mad5Anaxa as compared to control mice.

Example 23

Vaccine Efficacy in a Subcutaneous Tumor Model--Therapeutic Setting with Established Tumor

[1038] This study is based on the results obtained in Example 10 as shown in FIGS. 17-19 and on the results obtained in Example 22 shown in FIG. 37. It was the goal of this study to evaluate the effect of Z13Mad5Anaxa (cf. Example 7) on an established tumor.

[1039] For this purpose, the s.c. model of B16-OVA melanoma cells was used. In this model tumor cells are spreading slowly, therefore allowing a bigger vaccination time window.

[1040] The first vaccination with the low dose of 0.5 nmol of Z13Mad5Anaxa was performed once the tumor was established and visible i.e. at day 14 after tumor cell implantation. A second vaccination was done at day 21.

[1041] Thus, C57BL/6 mice were implanted s.c. with 1.times.10.sup.5 B16-OVA tumor cells in the left flank and vaccinated twice (d14 and d21) by s.c. injection of 0.5 nmol of Z13Mad5Anaxa in the right flank. Tumor growth and survival curves were monitored. Results are shown in FIG. 38.

[1042] The results indicate that Z13Mad5Anaxa efficaciously controls the growth of an established and visible tumor. Moreover, despite an established and visible tumor survival rates increased in mice treated with Z13Mad5Anaxa as compared to controls.

Example 24

Vaccine Efficacy in a Subcutaneous Tumor Model--Therapeutic Setting: Effect of the CPP

[1043] The protocol of this study corresponds to the study described in Example 10, with the difference that an additional group "Mad5Anaxa" (cf. Example 16) was evaluated.

[1044] Briefly, a benchmark tumor model was used, namely the s.c. implantation of EG.7-OVA thymoma cells. C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank. After tumor implantation, groups of 7 mice each were vaccinated s.c. in the right flank at day 5 and 13 by subcutaneous injection of 0.5 nmol of either Z13Mad5Anaxa (group 1) or Mad5Anaxa (group 2) and compared to a control group. Tumor size was measured with a caliper. Results are shown in FIG. 39.

[1045] The results show that the mice treated with Z13Mad5Anaxa show a significantly decreased tumor volume and a significantly increased survival rate compared to both, control mice and mice treated with Mad5Anaxa, i.e. a construct without CPP. These results indicate that the presence of a CPP results in significantly decreased tumor volume and a significantly increased survival rate, i.e. in increased efficiency of vaccination. Therefore, the results indicate--together with the results obtained in Example 10--that the presence of a CPP and the TLR agonist exert a synergic effect on tumor growth and survival rate.

Example 25

Comparison of the Kinetic of Immune Responses with Complexes having Different Cell Penetrating Peptides

[1046] To investigate the effect of different CPPs in the complex according to the present invention the fusion protein Z13Mad5Anaxa as described above (cf. Example 7) was used.

[1047] In addition, further fusion proteins were designed, which comprise CPPs other than Z13--namely Z14 (SEQ ID NO: 7) or Z18 (SEQ ID NO: 11). Those fusion proteins also comprise the protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR2 peptide agonist "Anaxa". Accordingly, the following constructs were additionally designed:

[1048] C57BL/6 mice were assigned to eight different groups (4 mice per group): three groups receiving 2 nmol of either Z13Mad5Anaxa, Z14Mad5Anaxa or Z18Mad5Anaxa and a respective control and three groups receiving 0.5 nmol of Z13Mad5Anaxa, Z14Mad5Anaxa or Z18Mad5Anaxa and a respective control. The mice were vaccinated five times (Week0, Week2, Week4, Week6 and Week8) s.c. Mice were bled 7 days after the 2.sup.nd, 3.sup.rd, 4.sup.th and 5.sup.th vaccination and multimer staining was performed (one experiment with 4 mice per group).

[1049] The results are shown in FIG. 40. All groups vaccinated with Z13Mad5Anaxa, Z14Mad5Anaxa or Z18Mad5Anaxa showed an increased percentage of multimer-positive cells compared to the control group (except for the second vaccination of Z18Mad5Anaxa). These results indicate that complexes according to the present invention having different cell penetrating peptides are able to elicit an immune response at different doses.

Example 26

Comparison of T Cell Immune responses with Complexes having Different Cell Penetrating Peptides

[1050] To investigate the CD8 T cell immune responses in more detail, C57BL/6 mice were assigned to three different groups (3-4 mice per group): naive, Z13Mad5Anaxa or Z14Mad5Anaxa.

[1051] C57BL/6 mice of the Z13Mad5Anaxa group and of the Z14Mad5Anaxa group were vaccinated five times (Week0, Week2, Week4, Week6 and Week8) s.c. with 2 nmol of either Z13Mad5Anaxa (cf. Example 7) or Z14Mad5Anaxa (cf. Example 25). Nine days after the 5.sup.th vaccination, mice were euthanized, organs recovered and multimer staining was performed to identify the percentage of SIINFEKL-specific CD8 T cells in the spleen, bone marrow and draining lymph nodes (inguinal and axillary).

[1052] The results are shown in FIG. 41. Mice vaccinated with Z13Mad5Anaxa or with Z14Mad5Anaxa showed a similar increase in multimer-positive cells, in particular in the spleen and bone marrow as well as a slight increase in draining lymph nodes.

[1053] To further investigate the CD8 T cell effector function after vaccination with complexes with different CPPs, in the same groups of mice as described above Elispot assay was performed on spleen cells stimulated with SIINFEKL OVACD8 peptide (SEQ ID NO: 35) nine days after the 5.sup.th vaccination in order to quantify IFN-.gamma. producing cells.

[1054] The results are shown in FIG. 42A. Mice vaccinated with Z13Mad5Anaxa showed a significant increase in IFN-.gamma. producing cells compared to naive mice. Mice vaccinated with Z14Mad5Anaxa showed also an increase in IFN-.gamma. producing cells compared to naive mice, however, the increase was not significant, which may be due to the low number of mice (3 mice in Z14Mad5Anaxa group).

[1055] To investigate the CD4 T cell responses after vaccination with complexes with different CPPs, in the same groups of mice as described above Elispot assay was performed on spleen cells stimulated with OVACD4 peptide (SEQ ID NO: 36) nine days after the 5.sup.th vaccination in order to quantify IFN-.gamma. producing cells.

[1056] The results are shown in FIG. 42B. Mice vaccinated with Z13Mad5Anaxa showed a highly significant increase in IFN-.gamma. producing cells compared to naive mice. Mice vaccinated with Z14Mad5Anaxa showed also an increase in IFN-.gamma. producing cells compared to naive mice, however, the increase was not significant, which may be due to the low number of mice (3 mice in Z14Mad5Anaxa group).

[1057] In addition, in the above described groups of mice, intracellular staining was performed on spleen cells stimulated with SIINFEKL OVACD8 peptide (SEQ ID NO: 35) to identify CD107a.sup.+IFN-.gamma..sup.+TNF-.alpha..sup.+ cells. Results are shown in FIG. 43. Mice vaccinated with Z13Mad5Anaxa or with Z14Mad5Anaxa showed a similar increase in CD107a.sup.+IFN-.gamma..sup.+TNF-.alpha..sup.+ cells.

Example 27

Comparison of the Effect of Complexes having Different Cell Penetrating Peptides on Tumor Growth and Survival in the EG.7-OVA s.c. Model

[1058] To investigate the effects of complexes having different cell penetrating peptides on tumor growth and survival the EG.7-OVA s.c. model was used. On d0 C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank and assigned to three different groups (naive, Z13Mad5Anaxa and Z14Mad5Anaxa). Mice were vaccinated twice at d5 and d13 after tumor implantation by s.c. injection of either 0.5 nmol of Z13Mad5Anaxa or Z14Mad5Anaxa in the right flank.

[1059] Results are shown in FIG. 44. Vaccination with Z13Mad5Anaxa or with Z14Mad5Anaxa resulted in significantly decreased tumor volumes compared to control mice (FIG. 44A) as well as to significantly increased survival rates compared to control mice (FIG. 44B). Those results indicate that both complexes, Z13Mad5Anaxa and Z14Mad5Anaxa, are able to significantly decrease tumor growth and to significantly prolong survival.

Example 28

Comparison of the Immune responses after Vaccination with Complexes having Different cell Penetrating Peptides

[1060] In this experiment the effect of different CPPs in the complex according to the present invention was investigated by using a complex with the TLR agonist "EDA". Therefore, the fusion protein EDAZ13Mad5 as described above (cf. Example 1) was used.

[1061] In addition, further fusion proteins were designed, which comprise CPPs other than Z13--namely Z14 (SEQ ID NO: 7) or Z18 (SEQ ID NO: 11). Those fusion proteins also comprise the protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR4 peptide agonist "EDA". Accordingly, the following constructs were additionally designed:

[1062] C57BL/6 mice were assigned to eight different groups (4 mice per group): three groups receiving 2 nmol of either EDAZ13Mad5, EDAZ14Mad5 or EDAZ18Mad5 and a respective control and three groups receiving 0.5 nmol of either EDAZ13Mad5, EDAZ14Mad5 or EDAZ18Mad5 and a respective control group. The mice were vaccinated three times (WeekO, Week2 and Week4) s.c. Mice were bled 7 days after the 2.sup.nd and 3.sup.rd vaccination and multimer staining was performed (one experiment with 4 mice per group).

[1063] The results are shown in FIG. 45. All groups vaccinated with EDAZ13Mad5, EDAZ14Mad5 or EDAZ18Mad5 showed an increased percentage of multimer-positive cells compared to the control group. These results indicate that complexes according to the present invention having different cell penetrating peptides are able to elicit an immune response at different doses.

Example 29

Effect of EDAZ14Mad5 on Tumor Growth and Survival in the EG.7-OVA s.c. Model

[1064] To investigate the effect of EDAZ14Mad5 on tumor growth and survival the EG.7-OVA s.c. model was used (cf. Example 4 and FIGS. 9-11 for the effect of EDAZ13Mad5 in the same model).

[1065] On d0 C57BL/6 mice were implanted s.c. with 3.times.10.sup.5 EG7-OVA tumor cells in the left flank and assigned to two different groups (naive and EDAZ14Mad5). Mice were vaccinated twice at d5 and d13 after tumor implantation by s.c. injection of 0.5 nmol of EDAZ14Mad5 in the right flank.

[1066] Results are shown in FIG. 46. Similarly to EDAZ13Mad5 (cf. Example 4, FIGS. 9-11) vaccination with EDAZ14Mad5 resulted in significantly decreased tumor volumes compared to control mice (FIG. 46A) as well as to significantly increased survival rates compared to control mice (FIG. 46B). Those results indicate that EDAZ14Mad5 is able to significantly decrease tumor growth and to significantly prolong survival--similarly to EDAZ13Mad5 (cf. Example 4, FIGS. 9-11).

Example 30

Superior Efficacy of Z13Mad5Anaxa Fusion Construct compared to Z13Mad5 and Anaxa in a Glioblastoma Model

[1067] To investigate the efficacy of a complex according to the present invention the glioblastoma model was chosen (cf. Example 20). Namely, Z13Mad5Anaxa (cf. Example 7; SEQ ID NO: 28) was administered to one group of mice, whereas Z13Mad5 (SEQ ID NO: 29) and Anaxa (SEQ ID NO: 15) were administered (both together) to another group of mice.

[1068] T cell homing at the tumor site was analyzed in Gl261-Quad tumor-bearing mice (7-16 mice per group) vaccinated twice, namely at day 7 and at day 21 after tumor implantation (day 0), with 2 nmol Z13Mad5Anaxa vaccine. A group vaccinated with both, Z13Mad5 and Anaxa (equimolar to Z13Mad5Anaxa), was used as control. Briefly, C57BL/6 mice were implanted i.c. (intracranially) with 5.times.10.sup.5 Gl261-Quad tumor cells and vaccinated twice (at d7 and d21 following implantation) by s.c. injection of 2 nmol of Z13Mad5Anaxa (group 1) or 2 nmol of Z13Mad5 and 2 nmol of Anaxa (group 2). At day 28, the blood and the brain infiltrating leukocytes (BILs) were analyzed, whereby SIINFEKL-specific CD8 T cells were quantified in blood and in BILs at d28 by multimer staining (7-16 mice per group).

[1069] Results are shown in FIG. 47. A significantly higher percentage of SIINFEKL-specific CD8 T cells was observed in the blood of Z13Mad5Anaxa-vaccinated mice as compared to mice vaccinated with both, Z13Mad5 and Anaxa (FIG. 47A). Similarly, a stronger accumulation of SIINFEKL-specific CD8 T cells was observed in the BILs of Z13Mad5Anaxa-vaccinated mice as compared to mice vaccinated with Z13Mad5 and Anaxa separately (FIG. 47B, p=0.0539).

[1070] Next, cytokine secretion was assessed. To this end, C57BL/6 mice were implanted i.c. with 5.times.10.sup.5 Gl261-Quad tumor cells and vaccinated twice (d7 and 21) by s.c. injection of 2 nmol of Z13Mad5Anaxa or 2 nmol of Z13Mad5 and 2 nmol of Anaxa. BILs were isolated and cultured during 6 h with matured BMDCs loaded or not with SIINFEKL peptide (SEQ ID NO: 35) in presence of BrefeldinA before intracellular staining for cytokines.

[1071] Results are shown in FIG. 48. In general, a high level of cytokine secretion was observed for brain-infiltrating CD8 T cells from mice vaccinated with Z13Mad5Anaxa. In particular, a significantly higher secretion of total IFN-.gamma. and of IFN-.gamma. and TNF-.alpha. together was observed for brain-infiltrating CD8 T cells from mice vaccinated with Z13Mad5Anaxa as compared to mice vaccinated with Z13Mad5 and Anaxa separately.

[1072] Taken together, these results demonstrate that Z13Mad5Anaxa vaccine (as compared to Z13Mad5 and Anaxa administered separately) was able to elicit a stronger SIINFEKL specific CD8 T cell immune response in the brain of tumor-bearing mice with potent effector function.

[1073] The results obtained are indicating that Z13Mad5Anaxa is efficacious for eliciting high brain infiltrating SIINFEKL-specific CD8 immune response. Z13Mad5Anaxa is able to promote the secretion of cytokine by antigen-specific CD8 T cells in the brain.

Example 31

Effect of another Antigenic Cargo in the Complex according to the Present Invention

[1074] To investigate the effect of a different antigenic cargo ("Mad8"), another complex comprising a cell penetrating peptide, different antigens and a TLR peptide agonist was designed ("Z13Mad8Anaxa"). Z13Mad8Anaxa differs from Z13Mad5Anaxa (described in Example 7) in the antigenic cargoes. In particular, "Z13Mad8Anaxa" is a fusion protein comprising the cell-penetrating peptide "Z13", the antigenic cargo "MAD8" comprising CD8 and CD4 epitopes of glycoprotein 70, and the TLR peptide agonist "Anaxa". In the following, the amino acid sequence of Z13Mad8Anaxa is shown with the cell-penetrating peptide "Z13" shown underlined and the TLR peptide agonist "Anaxa" shown in italics:

[1075] Naive Balb/c mice (4 mice per group) were vaccinated four times s.c. (week0, week2, week4 and week6 with 2 nmol of Z13Mad8Anaxa.

[1076] To investigate the CD4 T cell responses after vaccination, one week after the 4.sup.th vaccination, mice were euthanized; organs recovered and ex vivo Elispot assay was performed on spleen cells stimulated with gp70CD4 peptide (SEQ ID NO: 64) or gp70CD8 peptide (SEQ ID NO: 65) in order to quantify IFN-.gamma.-producing epitope-specific CD4 and CD8 T cells.

[1077] The results are shown in FIG. 49. Mice vaccinated with Z13Mad8Anaxa showed a significant increase in IFN-.gamma.-producing cells compared to naive mice. These data show that Z13Mad8Anaxa vaccine was able to elicit potent epitope-specific CD8 and CD4 T cell immune response and thus that the complex according to the present invention is able to elicit self-antigen immune response.

Example 32

Effect of another Antigenic Cargo in the Complex according to the Present Invention

[1078] To investigate the effect of a further different antigenic cargo ("Mad11"), another complex comprising a cell penetrating peptide, different antigens and a TLR peptide agonist was designed ("Z13Mad11Anaxa"). Z13Mad11Anaxa differs from Z13Mad5Anaxa (described in Example 7) in the antigenic cargoes. In particular, "Z13Mad11Anaxa" is a fusion protein comprising the cell-penetrating peptide "Z13", the antigenic cargo "MAD11" comprising two CD8 epitopes of surviving as described in Derouazi M, Wang Y, Marlu R, et al. Optimal epitope composition after antigen screening using a live bacterial delivery vector: Application to TRP-2. Bioengineered Bugs. 2010; 1(1):51-60. doi:10.4161/bbug.1.1.9482, and the TLR peptide agonist "Anaxa". In the following, the amino acid sequence of Z13Mad11Anaxa is shown with the cell-penetrating peptide "Z13" shown underlined and the TLR peptide agonist "Anaxa" shown in italics:

[1079] Naive C57BL/6 mice (5 mice per group) were implanted i.v. with 1.times.10.sup.5 B16 melanoma tumor cells and vaccinated twice (d0 and d10) by subcutaneous injection of 1 nmol of Z13Mad11Anaxa. On day18 mice were euthanized, organs recovered and ex vivo Elispot assay was performed on spleen cells stimulated with survivin peptides survivin20-28 (SEQ ID NO: 67) and survivin97-104: (SEQ ID NO: 68) in order to quantify IFN-.gamma. producing survivin-specific T cells.

[1080] The results are shown in FIG. 50. Mice vaccinated with Z13Mad11Anaxa showed less metastasis compared to naive mice (FIG. 50A). Moreover, in the spleen of mice vaccinated with Z13Mad11Anaxa significantly higher numbers of IFN-.gamma. producing survivin-specific T cells were observed (FIG. 49B).

[1081] The results obtained show that Z13Mad11Anaxa is efficacious for reducing the number of metastasis and Z13Mad11Anaxa is able to promote the secretion of cytokines by antigen-specific CD8 T cells in the spleen.

Example 33

Effect of another Antigenic Cargo in the Complex according to the Present Invention

[1082] To investigate the effect of a further different antigenic cargo ("Mad9"), another complex comprising a cell penetrating peptide, a different antigen and a TLR peptide agonist was designed ("Z13Mad9Anaxa"). Z13Mad9Anaxa differs from Z13Mad5Anaxa (described in Example 7) in the antigenic cargo. In particular, "Z13Mad9Anaxa" is a fusion protein comprising the cell-penetrating peptide "Z13", the antigenic cargo "Mad9" comprising the neoantigen as identified by Yadav et al. Nature. 2014 Nov. 27; 515(7528):572-6 from MC-38 tumor cell line, and the TLR peptide agonist "Anaxa". In the following, the amino acid sequence of Z13Mad9Anaxa is shown with the cell-penetrating peptide "Z13" shown underlined and the TLR peptide agonist "Anaxa" shown in italics:

[1083] Naive C57BL/6 mice (4 mice per group) were vaccinated four times s.c. (week0, week2, week4 and week6 with 2 nmol of Z13Mad9Anaxa. To investigate the CD8 T cell responses after vaccination, one week after the 4.sup.th vaccination, mice were euthanized, organs recovered and Elispot assay was performed on spleen cells after a 7-day in vitro restimulation with stimulated with adpgk peptide (SEQ ID NO: 66) in order to quantify to quantify IFN-.gamma.-producing epitope-specific CD8 T cells.

[1084] The results are shown in FIG. 51. Mice vaccinated with Z13Mad9Anaxa showed a significant increase in effector neoantigen-specific CD8 T cells compared to naive mice.

Example 34

Comparison of the Immune responses after Vaccination with Complexes having Different Cell Penetrating Peptides

[1085] In this experiment the effect of a further different CPP in the complex according to the present invention was investigated by using a complex with the TLR agonist "Anaxa". Therefore, the fusion protein Z13Mad5Anaxa as described above (cf. Example 7, SEQ ID NO: 28) was used.

[1086] In addition, a further fusion protein was designed, which comprise the TAT CPP combined to furin linkers as described in Lu et al., Multiepitope trojan antigen peptide vaccines for the induction of antitumor CTL and Th immune responses J. Immunol., 172 (2004), pp. 4575-4582. That fusion protein also comprises the protein "MAD5", which consists of different CD8.sup.+ and CD4.sup.+ epitopes from various antigens, and the TLR4 peptide agonist "Anaxa". Accordingly, the following construct was additionally designed:

TABLE-US-00041 TatFMad5Anaxa Sequence: (SEQ ID NO: 46) RKKRRQRRRRVKRISQAVHAAHAEINEAGRRVKRKVPRNQDWLRVKRA SFEAQGALANIAVDKARVKRSIINFEKLRVKRSTVHEILCKLSLEGDHS TPPSAYGSVKPYTNFDAE

[1087] C57BL/6 mice were assigned to three different groups (8 mice per group): one group receiving 2 nmol of Z13Mad5Anaxa, one group receiving 2 nmol of TatFMad5Anaxa and a respective control. The mice were vaccinated two times (Week0 and Week2) s.c. with either 2 nmol of Z13Mad5Anaxa or 2 nmol of TatFMad5Anaxa. Mice were bled 7 days after the 2.sup.nd vaccination and multimer staining was performed (8 mice per group).

[1088] The results are shown in FIG. 52. Mice vaccinated with Z13Mad5Anaxa or TatFMad5Anaxa showed an increased percentage of multimer-positive cells compared to the control group. These results indicate that complexes according to the present invention having different cell penetrating peptides are able to elicit an immune response at different doses. However, the CPP derived from ZEBRA (Z13) was better than the TAT CPP.

Example 35

Superior Efficacy of Z13Mad5Anaxa Fusion Construct compared to Z13Mad5 and Anaxa in Naive Mice

[1089] Next, the efficacy of a complex according to the present invention was investigated in naive mice. Namely, Z13Mad5Anaxa (cf. Example 7; SEQ ID NO: 28) was administered to one group of mice, whereas Z13Mad5 (SEQ ID NO: 29) and Anaxa (SEQ ID NO: 15) were administered (both together) to another group of mice.

[1090] C57BL/6 mice of the Z13Mad5Anaxa group and of the Z13Mad5+Anaxa group were vaccinated once (Week0) by s.c. injection of 2 nmol of Z13Mad5Anaxa (group 1) or 2 nmol of Z13Mad5 and 2 nmol of Anaxa (group 2). At day 14, the blood was analyzed, whereby SIINFEKL-specific CD8 T cells were quantified in blood by multimer staining (4-8 mice per group).

[1091] Results are shown in FIG. 53. A significantly higher percentage of SIINFEKL-specific CD8 T cells was observed in the blood of Z13Mad5Anaxa-vaccinated mice as compared to mice vaccinated with Z13Mad5 and Anaxa separately (FIG. 53).

[1092] Taken together, these results demonstrate that Z13Mad5Anaxa vaccine (as compared to Z13Mad5 and Anaxa administered separately) was able to elicit a stronger SIINFEKL specific CD8 T cell immune response in the periphery.

Example 36

Effect of another Antigenic Cargo in the Complex according to the Present Invention

[1093] To investigate the effect of a further different antigenic cargo ("Mad12"), another complex comprising a cell penetrating peptide, a different antigen and a TLR peptide agonist was designed ("Z13Mad12Anaxa"). Z13Mad12Anaxa differs from Z13Mad5Anaxa (described in Example 7) in the antigenic cargo. In particular, "Z13Mad12Anaxa" is a fusion protein comprising the cell-penetrating peptide "Z13", the antigenic cargo "MAD12" comprising three neoantigens as identified by Yadav et al. Nature. 2014 Nov. 27; 515(7528):572-6 from MC-38 tumor cell line, and the TLR peptide agonist "Anaxa". In the following, the amino acid sequence of Z13Mad12Anaxa is shown:

Naive C57BL/6 mice (4 mice per group) were vaccinated twice s.c. (week0, week2) with 2 nmol of Z13Mad12Anaxa. To investigate the CD8 T cell responses after vaccination, one week after the 2.sup.nd vaccination, the blood was analyzed, whereby neoantigen reps1-specific CD8 T cells were quantified in blood by multimer staining (4 mice per group).

[1094] The results are shown in FIG. 54. Mice vaccinated with Z13Mad12Anaxa showed a significant increase in effector neoantigen-specific CD8 T cells compared to naive mice.

Example 37

In Vitro Human Dendritic Cell Maturation

[1095] The goal of this study was to investigate the capacity of a complex for use according to the present invention ("Z13Mad5Anaxa", SEQ ID NO: 28, cf. Example 7) to induce maturation of dendritic cells in comparison to a complex lacking a TLR peptide agonist ("Z13Mad5", SEQ ID NO: 29, cf. Example 1).

[1096] The Z13Mad5Anaxa polypeptide and the Z13Mad5 polypeptide were investigated for their capacity to induce human dendritic cell (DC) maturation. After incubation over night with 300 nM of protein, activation markers expression (CD86, CD80, CD83 and HLA-DR) was assessed on the human DCs by FACS (FIG. 55). Same buffer volumes of each protein were used as negative controls.

[1097] Results are shown in FIG. 55. Whereas Z13Mad5Anaxa induced maturation of human DCs, shown by the up-regulation of CD86, HLADR and CD83, Z13Mad5 was not able to activate human DCs. These results indicate that the Anaxa portion of the protein is responsible for the up-regulation of the activation markers on the human DCs.
